Safety Relays Monitoring Safety Relays Minotaur MSR23M Specifications Description The MSR23M control unit is designed to monitor 4 wire safety mats that are connected together to form a safeguarded zone. The size of the safeguarded zone is limited by the total input impedance (100 ohms maximum) created by the wiring and connections. The controller is designed to interface with the control circuit of the machine and includes two safety relays to ensure control redundancy.
