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.
