Instead, it provides <strong>64 independent relay-driver channels<\/strong> that can control external relays when the voltage, current, contact configuration, or switching requirements exceed the capabilities of standard integrated PXI relay modules.\n<\/p>\n<p>\nWith an external power supply, the PXI-2567 supports drive voltages up to <strong>50 VDC<\/strong> and drive current up to <strong>600 mA per channel<\/strong>. The module supports up to <strong>25 A total drive current<\/strong> and incorporates overcurrent, overvoltage, overtemperature, and flyback protection for reliable control of inductive loads.\n<\/p>\n<h3>Product Overview<\/h3>\n<p>\n\u0417\u0435\u043c\u043b\u044f <strong>National Instruments PXI-2567<\/strong> provides a flexible interface between a PXI automated test system and externally mounted relays or other compatible loads.\n<\/p>\n<p>\nA typical system architecture is:\n<\/p>\n<p>\n<strong>PXI Controller \u2192 PXI-2567 \u2192 External Relay Coil \u2192 External Relay Contacts \u2192 DUT Signal<\/strong>\n<\/p>\n<p>\nIn this architecture, the PXI-2567 controls the relay coil while the external relay contacts perform the actual signal switching.\n<\/p>\n<p>\nThis allows system designers to select external relays according to the specific electrical requirements of the application, including:\n<\/p>\n<ul>\n<li>High-current switching<\/li>\n<li>High-voltage switching<\/li>\n<li>RF signal switching<\/li>\n<li>Multipole switching<\/li>\n<li>Power switching<\/li>\n<li>Custom switching topologies<\/li>\n<\/ul>\n<h3>Key Features<\/h3>\n<h4>64 Independent Relay Driver Channels<\/h4>\n<p>\nThe PXI-2567 provides <strong>64 independent relay-driver channels<\/strong>.\n<\/p>\n<p>\nThe channels are organized into <strong>eight banks of eight channels<\/strong>, providing high channel density for automated relay-control applications.\n<\/p>\n<p>\nThis architecture is useful when a test system contains many externally mounted relays that need to be controlled independently through software.\n<\/p>\n<h4>Up to 50 VDC External Drive Voltage<\/h4>\n<p>\nWhen used with an appropriate external power supply, the PXI-2567 supports a maximum external drive voltage of <strong>50 VDC<\/strong>.\n<\/p>\n<p>\nThis allows the module to control compatible relay coils requiring drive voltages beyond the internal PXI backplane supply options.\n<\/p>\n<p>\nThe actual external supply voltage should always match the electrical requirements of the connected relay or load.\n<\/p>\n<h4>Up to 600 mA Drive Current Per Channel<\/h4>\n<p>\nEach PXI-2567 driver channel supports up to <strong>600 mA maximum drive current<\/strong>.\n<\/p>\n<p>\nThis relatively high per-channel current capability allows the module to drive many types of external relay coils and compatible inductive loads.\n<\/p>\n<p>\nThe connected load must remain within both the individual channel limit and total module current limit.\n<\/p>\n<h4>Up to 25 A Total Module Drive Current<\/h4>\n<p>\nThe PXI-2567 supports up to <strong>25 A maximum total module drive current<\/strong> when operating within the specified electrical and thermal conditions.\n<\/p>\n<p>\nSystem designers should evaluate simultaneous channel activation carefully when a large number of high-current relay coils are energized at the same time.\n<\/p>\n<h4>Internal 5 V and 12 V Drive Power<\/h4>\n<p>\nThe PXI-2567 can use power available from the PXI backplane for compatible low-power relay-drive applications.\n<\/p>\n<p>\nInternal drive power includes:\n<\/p>\n<ul>\n<li><strong>5 V at up to 1.25 A<\/strong><\/li>\n<li><strong>12 V at up to 0.5 A<\/strong><\/li>\n<\/ul>\n<p>\nFor applications requiring higher voltage or greater total drive power, an appropriate external power supply can be used.\n<\/p>\n<h4>External Power Supply Support<\/h4>\n<p>\nOne of the major advantages of the PXI-2567 is its ability to operate with an external power source.\n<\/p>\n<p>\nThis provides additional flexibility when external relays require different coil voltages or greater drive power than the PXI backplane can provide.\n<\/p>\n<p>\nA typical architecture is:\n<\/p>\n<p>\n<strong>External DC Supply + PXI-2567 Driver Channel \u2192 Relay Coil<\/strong>\n<\/p>\n<h4>Overcurrent Protection<\/h4>\n<p>\nThe PXI-2567 includes per-channel protection circuitry for abnormal current conditions.\n<\/p>\n<p>\nThis helps protect the relay-driver circuitry when connected loads create excessive current conditions.\n<\/p>\n<h4>Overvoltage Protection<\/h4>\n<p>\nThe module also incorporates overvoltage protection.\n<\/p>\n<p>\nAccording to the PXI-2567 specifications, the per-channel overvoltage protection circuitry activates at up to approximately <strong>80 V maximum<\/strong>.\n<\/p>\n<p>\nThis protection threshold should not be interpreted as the normal operating voltage. The specified maximum external drive voltage remains <strong>50 VDC<\/strong>.\n<\/p>\n<h4>Flyback Protection for Inductive Loads<\/h4>\n<p>\nRelay coils, motors, solenoids, and similar inductive devices can generate voltage transients when current is interrupted.\n<\/p>\n<p>\nThe PXI-2567 incorporates protection against these inductive flyback conditions.\n<\/p>\n<p>\nThis makes the module particularly suitable for controlling:\n<\/p>\n<ul>\n<li>Relay coils<\/li>\n<li>Small DC motors<\/li>\n<li>Solenoid-type loads<\/li>\n<li>Other compatible inductive devices<\/li>\n<\/ul>\n<h4>Overtemperature Protection<\/h4>\n<p>\nThe PXI-2567 includes thermal protection circuitry to help protect the driver electronics from excessive operating temperatures.\n<\/p>\n<p>\nThermal loading should still be considered when many high-current channels operate simultaneously.\n<\/p>\n<h4>Fast Channel Operation<\/h4>\n<p>\nThe PXI-2567 provides a typical single-channel operate time of approximately <strong>60 \u03bcs<\/strong> under specified test conditions.\n<\/p>\n<p>\nThe module is therefore capable of rapidly controlling external relay-drive signals as part of automated test sequences.\n<\/p>\n<h4>Hardware Scanning<\/h4>\n<p>\nThe PXI-2567 supports scanning functionality for automated test applications.\n<\/p>\n<p>\nA predefined list of relay-driver connections can be downloaded to the switching hardware and executed according to hardware triggers.\n<\/p>\n<p>\nThis reduces host-processor interaction and can improve throughput in automated test systems.\n<\/p>\n<h4>78-Pin D-SUB Connectivity<\/h4>\n<p>\nThe PXI-2567 uses a <strong>78-pin D-SUB connector<\/strong> for its primary external relay-driver connections.\n<\/p>\n<p>\nAppropriate mating connectors, backshells, cables, or custom interface assemblies can be used to connect the module to external relay banks and test-system wiring.\n<\/p>\n<h3>Technical

High<\/strong><\/td>\n<td>Topology Dependent<\/td>\n<\/tr>\n<\/table>\n<h3>How Does the PXI-2567 Work?<\/h3>\n<p>\nThe PXI-2567 acts as an interface between software commands from the PXI system and external relay coils.\n<\/p>\n<p>\nA simplified signal chain is:\n<\/p>\n<p>\n<strong>Test Software \u2192 PXI-2567 Driver \u2192 External Relay Coil \u2192 Relay Contact Changes State \u2192 DUT Signal Routed<\/strong>\n<\/p>\n<p>\nThe PXI-2567 controls the coil. The electrical characteristics of the actual switched DUT signal are primarily determined by the external relay selected by the system designer.\n<\/p>\n<h3>Why Use External Relays?<\/h3>\n<p>\nStandard PXI switch modules are convenient when their built-in relay topology and electrical specifications meet the application requirements.\n<\/p>\n<p>\nHowever, some test systems require specialized relays for:\n<\/p>\n<ul>\n<li>Higher switching current<\/li>\n<li>Higher switching voltage<\/li>\n<li>RF and microwave signals<\/li>\n<li>Multiple poles<\/li>\n<li>Special contact arrangements<\/li>\n<li>High-power switching<\/li>\n<li>Custom fault insertion<\/li>\n<li>Application-specific isolation<\/li>\n<\/ul>\n<p>\nThe PXI-2567 allows these external relays to remain under software control from the PXI system.\n<\/p>\n<h3>External Relay Control<\/h3>\n<p>\nExternal relay control is the primary application of the PXI-2567.\n<\/p>\n<p>\nEach driver channel can control a compatible relay coil independently.\n<\/p>\n<p>\n\u041d\u0430\u043f\u0440\u0438\u043c\u0435\u0440:\n<\/p>\n<p>\n<strong>PXI-2567 Channel 0 \u2192 Relay 0 Coil<\/strong><br \/>\n<strong>PXI-2567 Channel 1 \u2192 Relay 1 Coil<\/strong><br \/>\n<strong>PXI-2567 Channel 2 \u2192 Relay 2 Coil<\/strong><br \/>\n<strong>&#8230;<\/strong><br \/>\n<strong>PXI-2567 Channel 63 \u2192 Relay 63 Coil<\/strong>\n<\/p>\n<p>\nThis provides centralized software control for large custom relay assemblies.\n<\/p>\n<h3>High-Current External Relay Systems<\/h3>\n<p>\nThe PXI-2567 can control external relays whose contacts are designed to switch currents beyond the capabilities of conventional PXI switch modules.\n<\/p>\n<p>\nIn this configuration:\n<\/p>\n<p>\n<strong>PXI-2567 \u2192 Controls Relay Coil<\/strong><br \/>\n<strong>External Relay \u2192 Switches High-Current DUT Circuit<\/strong>\n<\/p>\n<p>\nThe PXI-2567 itself does not carry the high-current DUT signal through its relay-driver channel.\n<\/p>\n<p>\nThis distinction is important when designing power switching and fault-insertion systems.\n<\/p>\n<h3>High-Voltage External Relay Systems<\/h3>\n<p>\nExternal relays can also be selected for applications requiring switching voltages beyond the direct signal-switching capabilities of standard PXI relay modules.\n<\/p>\n<p>\nThe PXI-2567 controls only the external relay coil, while the external relay contacts handle the DUT signal.\n<\/p>\n<p>\nTherefore, the maximum DUT switching voltage is determined by the selected external relay and the complete system design rather than by treating the PXI-2567 as a direct high-voltage signal switch.\n<\/p>\n<h3>RF Relay Control<\/h3>\n<p>\nThe PXI-2567 can control compatible external RF relays or RF switching assemblies.\n<\/p>\n<p>\nA typical architecture is:\n<\/p>\n<p>\n<strong>PXI-2567 \u2192 RF Relay Coil<\/strong><br \/>\n<strong>RF Instrument \u2192 RF Relay Contacts \u2192 DUT<\/strong>\n<\/p>\n<p>\nThis allows specialized RF relays to be incorporated into a PXI-controlled automated RF test system.\n<\/p>\n<p>\nRF bandwidth, insertion loss, isolation, VSWR, RF power, and connector characteristics are determined primarily by the external RF relay and associated signal path.\n<\/p>\n<h3>Small DC Motor Control<\/h3>\n<p>\nThe PXI-2567 can also drive compatible small DC motors within its specified voltage and current limits.\n<\/p>\n<p>\nThis capability can be useful in automated test fixtures containing small mechanical actuators or positioning mechanisms.\n<\/p>\n<p>\nMotor starting current and inductive characteristics should be evaluated carefully before connecting the load.\n<\/p>\n<h3>Inductive Load Control<\/h3>\n<p>\nThe PXI-2567 is particularly useful for loads with inductive characteristics.\n<\/p>\n<p>\nExamples can include:\n<\/p>\n<ul>\n<li>Relay coils<\/li>\n<li>Small DC motors<\/li>\n<li>Compatible solenoids<\/li>\n<li>Electromagnetic actuators<\/li>\n<\/ul>\n<p>\nIts integrated flyback protection helps manage voltage transients generated when current through an inductive load is interrupted.\n<\/p>\n<h3>PXI-2567 for Automated Test Equipment<\/h3>\n<p>\nAutomated test equipment often contains custom switching assemblies that cannot be implemented efficiently with standard PXI switch modules.\n<\/p>\n<p>\nThe PXI-2567 provides a scalable way to control these external switching devices directly from the PXI system.\n<\/p>\n<p>\nTypical ATE applications include:\n<\/p>\n<ul>\n<li>Automotive ECU testing<\/li>\n<li>Electronic module validation<\/li>\n<li>Power electronics testing<\/li>\n<li>Aerospace electronics test<\/li>\n<li>Fault insertion systems<\/li>\n<li>Production functional test<\/li>\n<li>Custom relay matrices<\/li>\n<\/ul>\n<h3>Fault Insertion Applications<\/h3>\n<p>\nThe PXI-2567 can control external relays used to implement custom fault-insertion architectures.\n<\/p>\n<p>\nDepending on the external relay arrangement, a system can simulate conditions such as:\n<\/p>\n<ul>\n<li>Open circuits<\/li>\n<li>Short circuits<\/li>\n<li>Signal disconnection<\/li>\n<li>Power interruption<\/li>\n<li>Alternate signal routing<\/li>\n<li>Custom electrical faults<\/li>\n<\/ul>\n<p>\nThis architecture can be useful for hardware-in-the-loop, automotive electronics, aerospace electronics, and system validation applications.\n<\/p>\n<h3>PXI-2567 for Automotive Test<\/h3>\n<p>\nAutomotive electronic control unit testing frequently requires large custom relay systems for signal routing and fault simulation.\n<\/p>\n<p>\nThe PXI-2567 can control external automotive-grade relays selected according to the voltage, current, isolation, and contact requirements of the test system.\n<\/p>\n<p>\nTypical applications can include:\n<\/p>\n<ul>\n<li>ECU functional testing<\/li>\n<li>Power distribution

external relay driver module designed to control external relays and compatible inductive loads from a PXI automated test system.\n<\/p>\n<h4>Is the PXI-2567 a relay switch module?<\/h4>\n<p>\nThe PXI-2567 is primarily a <strong>relay driver<\/strong>, not a conventional signal-switching relay module. It controls external relay coils, while the external relay contacts perform the actual DUT signal switching.\n<\/p>\n<h4>How many channels does the PXI-2567 have?<\/h4>\n<p>\nThe PXI-2567 provides <strong>64 independent driver channels<\/strong> organized into eight banks of eight channels.\n<\/p>\n<h4>What is the maximum drive voltage of the PXI-2567?<\/h4>\n<p>\nWhen using an appropriate external power supply, the maximum specified external drive voltage is <strong>50 VDC<\/strong>.\n<\/p>\n<h4>What is the maximum current per channel?<\/h4>\n<p>\nEach PXI-2567 channel supports up to <strong>600 mA maximum drive current<\/strong>.\n<\/p>\n<h4>What is the maximum total current of the PXI-2567?<\/h4>\n<p>\nThe maximum total module drive current is <strong>25 A<\/strong> under the specified operating conditions.\n<\/p>\n<h4>Can the PXI-2567 use an external power supply?<\/h4>\n<p>\nYes. External power support is one of the primary features of the PXI-2567 and allows compatible relay coils requiring up to 50 VDC to be controlled.\n<\/p>\n<h4>Does the PXI-2567 provide internal power?<\/h4>\n<p>\nYes. The module provides access to internal PXI power for compatible applications, including 5 V at up to 1.25 A and 12 V at up to 0.5 A total.\n<\/p>\n<h4>Can the PXI-2567 drive a DC motor?<\/h4>\n<p>\nYes. NI specifies that the PXI-2567 can drive compatible small DC motors and other inductive loads, provided their electrical requirements remain within the module&#8217;s limits.\n<\/p>\n<h4>Can the PXI-2567 control RF relays?<\/h4>\n<p>\nYes. The PXI-2567 can control compatible external RF relay coils. The RF signal itself passes through the external relay, so RF frequency, insertion loss, isolation, VSWR, and RF power capability depend on the selected relay and signal path.\n<\/p>\n<h4>Does the PXI-2567 have flyback protection?<\/h4>\n<p>\nYes. The PXI-2567 includes protection for inductive flyback voltage generated when relay coils and other inductive loads are switched off.\n<\/p>\n<h4>Does the PXI-2567 have overcurrent protection?<\/h4>\n<p>\nYes. The module includes per-channel overcurrent protection as part of its protection circuitry.\n<\/p>\n<h4>What connector does the PXI-2567 use?<\/h4>\n<p>\nThe PXI-2567 uses a <strong>78-pin D-SUB connector<\/strong> for its primary external driver connections.\n<\/p>\n<h4>What is the difference between PXI-2567 and PXI-2568?<\/h4>\n<p>\nThe PXI-2567 is a 64-channel external relay driver used to control external relay coils. The PXI-2568 is a 31-channel SPST relay switch containing onboard relays for directly switching compatible DUT signals. They are designed for fundamentally different switching architectures.\n<\/p>\n<h4>Can the PXI-2567 be used for fault insertion?<\/h4>\n<p>\nYes. The PXI-2567 can control external relay assemblies designed to implement open circuits, short circuits, power interruptions, and other compatible fault conditions in automated test systems.\n<\/p>\n<h4>What is the part number of the PXI-2567?<\/h4>\n<p>\nThe NI ordering part number for the PXI-2567 is <strong>778572-67<\/strong>.\n<\/p>\n<h4>What should I check before purchasing a PXI-2567?<\/h4>\n<p>\nBefore purchasing the PXI-2567, verify the number of required relay-driver channels, relay coil voltage and current, simultaneous channel requirements, total current, internal or external power requirements, external relay topology, inductive load characteristics, D-SUB connectivity, PXI chassis compatibility, and software requirements.\n<\/p>\n<h3>\u0417\u0430\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435<\/h3>\n<p>\n\u0417\u0435\u043c\u043b\u044f <strong>NI PXI-2567 64-Channel PXI External Relay Driver Module<\/strong> provides a flexible way to control large numbers of external relays and compatible inductive loads from a PXI automated test system. With 64 independent channels, up to 50 VDC external drive voltage, up to 600 mA per-channel drive current, a 25 A total module limit, internal and external power options, and integrated protection
