Digital I/O Devices

NI digital I/O devices offer a variety of channel, current, and voltage options so users can find the best fit for their application needs. The I/O devices provide a high-reliability feature set designed to automate even the most demanding applications. Programmable input filters remove chatter, noise, glitches, and spikes on inputs while also providing debouncing for digital switches and relays. Programmable power-up states provide a known initialized state for safe operation when connected to pumps, motors, and other industrial actuators or machinery. Digital I/O watchdogs provide a failsafe mechanism that monitors for computer or application crashes and places the system in a state to ensure a safe recovery. Models also offer high-voltage, high-current, and isolation options to ensure the product can work safely in many environments.
