Description
The MSR142RTP 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 MSR142RTP
checks for cross faults across the two inputs. When connected to
light curtains, the light curtain must perform the cross fault
detection.
The MSR142RTP 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 MSR142RTP 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 MSR142RTP
checks the output monitoring circuit through the manual application
of the reset switch.
The outputs include 7 normally open safety rated outputs, 4
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 outputs are non-safety
output intended to provide an external signal about the status of the
safety outputs.
