Minotaur MSR127RTP Safety Relay, Single Channel
The MSR127RTP is a single function safety relay that 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 configuration, 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 relay has a monitored manual reset whereas the MSR127TP relay 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 of the relay include three normally open safety-rated outputs as well as one normally closed auxiliary output. The safety outputs have independent and redundant internal contacts to support the safety function. The auxiliary output is a non-safety output intended to provide an external signal about the status of the safety outputs.
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 to light curtains, the light curtain must perform the cross fault detection.
