Safety Relays Monitoring Safety Relays Minotaur MSR18T Specifications Description The Minotaur MSR18T is a monitoring safety relay unit with dual channel input, 5 safety outputs and 2 auxiliary outputs. It is designed for operation as E-Stop, safety gate applications, and 2-hand control applications. The MSR18T is a versatile unit with extensive diagnostics. It can be used with E-Stop buttons, gate interlocks, two-hand controls as well as expansion relays when additional inputs are needed. When used in a suitably configured circuit, the MSR18T provides additional safety rated output circuits with checking and monitoring of its status. Safety critical faults or power failures will cause them to initiate a lock-out to a safe state.
