Safety Relays
Monitoring Safety Relays with Delayed Outputs
Minotaur MSR138DP
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.
