The Yokogawa MRI214 is a Relay Input Board.

This MRI214  board is used to interface with external relays or contacts, enabling the control system to read status information or detect changes in external devices through relay input signals. The MRI214 module plays a critical role in applications where relay-based control signals need to be integrated into the DCS for monitoring or control purposes.

The Yokogawa MRI214 Relay Input Board provides a robust interface for accepting digital signals from external relay contacts. 

Model: MRI214

Manufacturer: Yokogawa

Type: Relay Input Board for Distributed Control Systems (DCS)

MRI214  provides 8 input channels for accepting relay contacts.

Input Type: Relay

Input Voltage Range:24V DC ±10%

Contact Rating:250V AC at 5A
