Safety Relays Monitoring Safety Relays Minotaur MSR131RTP Specifications Description The MSR131RTP is a versatile monitoring safety relay. It can be connected in four different input wiring configurations: 1 N.C., 2 N.C., 2 PNP connections from a light curtain, or a four wire safety mat. When connected in the 2 N.C. fashion, the MSR131RTP checks for cross faults across the two inputs. When connected to light curtains, the light curtain must perform the cross fault detection. The MSR131RTP has output monitoring that can accommodate either automatic/manual reset or a monitored manual reset. When configured with automatic/manual reset (jumpers on X1-X2 and X3-X4), the MSR131RTP can have the reset terminals S33-S34 jumpered or can be converted to an unmonitored manual reset by adding a normally open switch in the monitoring loop (S33-S34). When configured to monitored manual reset, the MSR131RTP checks the output monitoring circuit through the manual application of the reset switch. The outputs include 3 normally open safety rated outputs, 2 normally closed auxiliary outputs, and 2 solid state outputs. One solid state output indicates that the inputs are closed. The second solid state output indicates that the safety outputs are active. 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.
