Minotaur 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.
