The PXI‑6511 is an industrial digital input interface, with eight banks of isolated channels. If a computer or application fault occurs, the PXI‑6511 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.
You can request repair, schedule calibration, or get technical support. A valid service agreement may be required.
