PCI-6259

The PCI-6259 is a PCI Multifunction I/O Device from National Instruments, designed for data acquisition, signal measurement, digital control, and automated test applications. As a high-channel-count M Series DAQ device, the NI PCI-6259 provides analog input, analog output, digital I/O, counter/timer, and triggering functions on a standard PCI platform. It features 32 analog input channels, 16-bit resolution, a maximum sampling rate of 1.25 MS/s, 4 analog output channels, and 48 digital I/O channels, making it suitable for laboratory automation, research, design verification, and manufacturing test applications. NI lists the PCI-6259 as no longer available and suggests PCIe-6353 as a replacement model.

The NI PCI-6259 is designed to digitize analog signals and control digital signals in PC-based measurement systems. Its analog input channels allow engineers to acquire voltage signals from sensors, circuits, test fixtures, and electronic devices. With 16-bit resolution, the PCI-6259 can capture reliable measurement detail for general-purpose data acquisition tasks. Its 1.25 MS/s maximum sampling rate makes it suitable for medium-speed signal acquisition where stable and repeatable measurements are required.

In addition to analog input capability, the PCI-6259 Multifunction I/O Device includes 4 analog output channels for generating voltage signals, control signals, or test stimulus signals. These analog outputs can be used for device control, sensor simulation, waveform generation, and automated test sequencing. The device also provides 48 digital I/O channels, allowing users to monitor digital states, control external equipment, communicate with test fixtures, and perform basic digital control operations in a PCI-based test system.

The National Instruments PCI-6259 also includes two 32-bit counter/timer channels, which can be used for event counting, pulse generation, frequency measurement, period measurement, and timing-related operations. These counter/timer functions are useful for automated test systems that require synchronized measurement, timing control, encoder measurement, or pulse-based testing. The device also supports analog and digital triggering, helping users build more flexible and synchronized DAQ systems.

The NI PCI-6259 supports correlated digital I/O and works with NI-DAQmx driver software. NI-DAQmx helps simplify hardware configuration, channel setup, sampling rate control, triggering, and measurement programming. The device can also be used with SCC or SCXI signal conditioning modules to add sensor measurement or high-voltage measurement capability, expanding the range of signals that can be acquired in a test system.

The PCI-6259 is suitable for many applications, including electronic circuit testing, laboratory automation, research measurement, production line monitoring, design validation, and manufacturing test. Because it combines analog input, analog output, digital I/O, and counter/timer functions in one PCI device, it is especially useful for mixed-signal test systems where multiple measurement and control functions are required.

Overall, the NI PCI-6259 PCI Multifunction I/O Device is a reliable general-purpose DAQ solution for users who need high-channel-count analog measurement, signal generation, digital control, timing functions, and PCI platform compatibility. With 32 AI channels, 4 AO channels, 48 DIO channels, 16-bit resolution, 1.25 MS/s sampling, and NI-DAQmx support, the PCI-6259 is well suited for automated test, laboratory measurement, and data acquisition applications.
