Emerson Ovation 5X00121G01 Discrete Input Module

The Emerson 5X00121G01 is a discrete input module developed for the Ovation DCS control system. It collects digital on-off status signals from field sensors, limit switches and valve feedback devices, and transmits digital data to the DCS main controller for logic judgment.

This module adopts industrial-grade circuit design with built-in filtering and surge protection. It supports channel self-diagnosis function and can resist various electromagnetic interference in industrial sites, widely used for DCS system expansion, technical transformation and spare parts replacement in power and process industries.
