The  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 with monitored manual reset provide checking of the 

output monitoring circuit.

The outputs 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 is a nonsafety output intended 

to provide an external signal about the status of the safety outputs.
