Description
Emerson 1C31219G01 Relay Output Module
The Emerson 1C31219G01 is a high-reliability relay output module designed for industrial automation systems, particularly Emerson’s Ovation™ distributed control system (DCS). This module provides a rugged interface between digital output signals from PLCs or controllers and high-power external devices, ensuring precise control in demanding environments such as power plants, oil refineries, and water treatment facilities.
1. Product Overview
The Emerson 1C31219G01 serves as a relay output module for Emerson’s Ovation™ system, supporting 16 channels of high-power relay outputs. It enables the conversion of low-voltage digital signals into high-current/voltage switching commands for actuators, motors, and solenoids. The module features a modular design, allowing easy integration with Ovation™ controllers and field devices. Its wide operating temperature range (-40°C to 70°C) and robust construction make it suitable for harsh industrial settings.
