Product Overview

PXI‑6512 is bank‑isolated industrial digital output module for PXI test‑and‑measurement platforms. It delivers 64 isolated source‑type digital outputs grouped into eight galvanically separated banks, protecting PXI host hardware from field‑side ground loops and voltage transients. Integrated watchdog function forces pre‑configured safe output levels upon software or host failure, critical for test‑stand safety interlock control. Widely deployed for manufacturing test systems, hardware‑in‑the‑loop simulation and industrial‑equipment validation setups. Surplus and refurbished tested spare DAQ hardware for test‑system maintenance and upgrade projectsNI.

Application Notes

‑ Install inside compliant PXI chassis; complete NI‑DAQmx driver installation before commissioning. ‑ Use shielded 100‑pin accessory cables for field‑signal wiring. ‑ Configure watchdog safety parameters within software before connecting actuators. ‑ Typical deployment: PXI‑based test‑system isolated digital‑output spare‑part stocking.
