The Yokogawa MRI114 is a Relay Output Board designed for use in Yokogawa’s CENTUM series of Distributed Control Systems (DCS), including CENTUM CS 3000 and CENTUM VP. This MRI114  module provides the necessary interface for controlling external devices using relay outputs, making it an essential component for in process control environments. The MRI114 board enables direct switching of external equipment, such as motors, alarms, and other electrical devices, in response to control system outputs.

The Yokogawa MRI114 Relay Output Board is part of the I/O modules for the CENTUM DCS platform. The board provides digital relay outputs, which are used to control external devices based on the signals from the DCS controller.

This MRI114  module is engineered to provide high operational flexibility, ease of installation, and reliable performance in demanding industrial environments.
