Rockwell Automation MSR127RTP Manual

Safety relay

MSR127RP/TP

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.

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.
