Minotaur MSR123RT

Description

The Allen-Bradley Guardmaster Minotaur MSR123RT is a safety monitoring relay that provides two normally open safety contacts and a solid state auxiliary output for use with interfacing to PLCs.The MSR123RT can be connected to either a single or dual channel safety gate or e-stop, or can be connected to a light curtain that provides cross fault detection.

Reset and output monitoring is determined by the wiring

configuration. Automatic/manual reset can use a jumper or can be used to check operation of external contactors. Monitored manual requires the use of a manually operated normally open momentary switch.

The MSR123RT has 2 normally open safety rated outputs. The safety outputs have independent and redundant internal contacts to help ensure the safety function. The solid state auxiliary output is a PNP circuit with short circuit protection designed to indicate the status of the MSR123RT.
