Product Description
Product Overview
The Emerson 1C31203G01+1C31204G01 is an Ovation Remote Node Controller assembly designed for use within Emerson’s Ovation Distributed Control System (DCS). This assembly combines the 1C31203G01 (Remote Node Controller Electronic Module, EMOD) with the 1C31204G01 (Remote Node Personality Module, PMOD) to facilitate remote I/O communication over fiber-optic media. Manufactured by Emerson, a leader in automation technologies, this module prepares messages from the main controller for local I/O modules at a remote node and sends responses back, enabling reliable data exchange in industrial applications. It is widely used in industries such as power generation, oil and gas, and process control, where distributed control and robust connectivity are essential. The assembly supports a fiber-optic range of up to 2 km, ensuring high-speed, noise-immune communication.
