Minotaur MSR126R/T
Description
The Allen-Bradley Guardmaster Minotaur MSR126R/T is a safety
monitoring relay that provides the very basics for safety control
systems in a 22.5mm package.
The MSR126R/T is designed for connection to a single channel
safety gate, a single channel e-stop or a light curtain that provides
cross fault detection. The MSR126.1R/T is designed for connection
to a dual channel safety gate or e-stop, as it performs cross fault
detection across the inputs.
The MSR126R and MSR126.1R are designed for applications where
a monitored manual reset is required. Monitored manual reset
requires the use of a manually operated normally open momentary
switch to activate the outputs.
The MSR126T and MSR126.1T are designed for applications where
automatic/manual reset is required. Automatic/manual reset allows
a jumper across the S33-S34 circuit, and therefore does not perform
output monitoring.
The outputs are only 2 normally open safety rated outputs. The
safety outputs have independent and redundant internal contacts to
help ensure the safety function.
