Relay Model Selected:   MSR127RP/TP

The Guardmaster® 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. Note that Guardmaster Safety Relays have been marketed by Rockwell Automation under the trade name "Minotaur" in the past.

Application:

MSR142RTP is a widely used safety monitoring relay.

Four different input wiring configurations can be used to connect the relay:

A two PNP link between a normally closed, two normally closed, light screen, or four line safety carpets.

When using two normally closed modes to link, MSR142RTP checks whether there is a cross fault between the two inputs.

When the screen is connected to the screen, the screen must perform cross fault detection.
