EMERSON 1C31113G01 is an 8-channel low level analog input module for Emerson Ovation DCS system, designed for ±20mV low-level signal acquisition, with 13-bit high resolution and channel isolation, widely used in power plant process monitoring.

Product Overview

EMERSON 1C31113G01 is an analog input I/O module of Emerson Ovation distributed control system. It features 8 isolated channels for collecting ±20mV low-level millivolt signals from field sensors such as thermocouples and strain gauges. The module adopts high-precision 13-bit ADC conversion, transmits acquired data to Ovation controller via backplane bus. It supports hot swap, convenient for online cabinet maintenance, commonly used in thermal power, petrochemical and other large process control systems.
