Safety Relays Monitoring Safety Relays with Delayed Outputs Minotaur MSR138DP Specifications Standards Description The MSR138DP is a versatile monitoring safety relay. It can be connected in four different input wiring configurations: 1 N.C., 2 N.C., or 2 PNP connections from a light curtain. When connected in the 2 N.C. fashion, the MSR138DP checks for cross faults across the two inputs. When connected to light curtains, the light curtain must perform the cross fault detection. The MSR138DP has output monitoring that can accommodate either automatic/manual reset or a monitored manual rest. When configured with automatic/manual reset (jumpers on X1-X2 and X3-X4), the MSR138DP 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 MSR138DP checks the output monitoring circuit through the manual application of the reset switch. The outputs of the MSR138DP include 2 normally open immediate safety outputs and 3 normally open delayed safety outputs. The outputs of the MSR138.1DP include 2 normally open immediate safety rated outputs, 2 normally open delayed safety outputs and 1 normally closed delayed safety output. The safety outputs have independent and redundant internal contacts to help ensure the safety function. A N.C. timer reset switch can be added to force the delayed contacts opened prior to the completion of the timing cycle. An electronic protection circuit detects shorts across the input, when the MSR138DP wired for cross fault detection.
