48-Channel, Sink/Source Inputs, Channel-Channel Isolated PXI Digital I/O Module—The PXI‑6529 is an industrial, parallel digital input interface. PXI‑6529 devices are ideal for a variety of applications from automotive design, industrial factory automation, and machine control to aerospace, laboratory research, and biomedical applications. With programmable power-up states, you can configure the initial output states in software to ensure safe operation when connected to industrial actuators. If a computer or application fault occurs, the PXI‑6529 can use digital I/O watchdogs to switch to a configurable safe output state to ensure detection and safe recovery from fault conditions. Programmable input filters eliminate glitches/spikes and provide debouncing for digital switches/relays through a software-selectable digital filter.
