Digital I/O Devices offer a variety of channel, current, and voltage options so that you can find the best fit for your application needs. They 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, and these filters also provide 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 fail-safe mechanism that monitors for computer or application crashes and place the system in a state to ensure safe recovery. Models also offer high-voltage, high-current, and isolation options to ensure the product can work safely in many environments.
