Description
The MSR127RTP can be connected in three different input wiring
configurations: one normally closed, two normally closed, or with
two PNP connections from a light curtain. When connected in the
two normally closed fashion, the MSR127RTP checks for cross
faults across the two inputs. When connected to light curtains, the
light curtain must perform the cross fault detection.

Auto./Manual or Monitored Manual
The MSR127RP has a monitored manual reset. The MSR127TP has
an automatic/manual reset. Models with automatic/manual reset can
have the reset jumpered or can be converted to an unmonitored
manual reset by adding a normally open switch in the monitoring
loop. Models with monitored manual reset provide checking of the
output monitoring circuit.

The outputs include three normally open safety-rated outputs as
well as one normally closed auxiliary output. The safety outputs
have independent and redundant internal contacts to support the
safety function. The auxiliary output is a nonsafety output intended
to provide an external signal about the status of the safety outputs.
