MSR124RT
|
Description
The Allen-Bradley Guardmaster Minotaur MSR124RT is a safety monitoring relay that provides versatile inputs and monitoring capability with a large number of safety outputs in a 100mm package.
The MSR124RT can be connected as 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 are determined by the wiring configuration. Automatic/manual reset can use a jumper or can be used to check operation of the contacts. Monitored manual requires the use of a manually operated normally open momentary switch to activate the outputs.
The outputs include 5 normally open safety rated outputs and 1 auxiliary output. The safety outputs have independent and redundant internal contacts to help ensure the safety function. The auxiliary output is not safety rated and shall only be used for indication purposes.
