Product Introduction
Земля NI PXI-6513 is a 64-channel optically isolated sinking digital output module designed for industrial automation, automated test equipment, production-line control, and electronic validation systems. Its high channel density allows engineers to control a large number of relays, indicators, actuators, solenoids, and other externally powered DC devices from a single PXI slot.
The PXI-6513 organizes its 64 output lines into eight isolated banks with eight channels per bank. Optical isolation between the I/O banks and the PXI bus helps protect the measurement system from ground potential differences, electrical noise, and industrial transients.
Product Overview
Земля PXI-6513 is part of the National Instruments industrial digital I/O family. Unlike standard TTL digital output modules, it uses isolated sinking outputs intended for externally powered industrial loads operating at voltages up to 30 VDC.
Each output bank uses a shared external supply and common connection. The sinking architecture switches the load current toward the bank common, making the module suitable for industrial devices designed for low-side switching.
The module supports programmable power-up states, allowing output channels to initialize to a predefined condition after system startup. NI-DAQmx software provides digital output configuration, channel control, diagnostics, and integration with LabVIEW, TestStand, Python, C/C++, and .NET applications.
