MSR127RP

The MSR127RTP can be connected in three different input wiring configurations: 1 N.C., 2 N.C., or with 2 PNP connections from a light curtain. When connected in the 2 N.C. 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 of MSR127RP with monitored manual reset provide checking of the
output monitoring circuit.

The outputs of MSR127RP include 3 normally open safety rated outputs as well as 1 normally closed auxiliary output. The safety outputs have independent and redundant internal contacts to help ensure the safety function. The auxiliary output of MSR127RP is a nonsafety output intended to provide an external signal about the status of the safety outputs.
