The MFRM board is part of the signaling board series manufactured by Hollysys. The signaling system in urban trains and metros enables intelligent traffic management with minimal human intervention, enhancing the speed and safety of communication lines.

Signaling systems are among the most sensitive and critical command components in urban train and metro traffic systems, and an error in their performance can have dangerous consequences.

Signaling systems in urban trains and metros consist of various input, output, interface, power supply, and processor boards. Each part of the system has a specific role.

The MFRM board is a multifunctional board responsible for controlling the internal power supplies of the signaling system.
