1C31116G02 | Emerson Industrial Digital Input Module for Ovation

Product Description

The Emerson Ovation 1C31116G02 is a high-performance digital input module designed for Emerson’s Ovation Distributed Control System (DCS). It acquires discrete signals from field devices such as limit switches, push buttons, relays, and contact sensors, converting them into accurate logic inputs for the Ovation controller.

Engineered for industrial environments, this module provides robust galvanic isolation, fast response times, and built-in diagnostics. Moreover, it simplifies system monitoring and ensures reliable signal acquisition, making it essential for power generation, petrochemical, water treatment, and other process industries.

Compact and industrial-grade, the 1C31116G02 integrates seamlessly into Ovation DCS racks, offering straightforward installation and high operational reliability.
