The Omron STI RM-1 Module provides force-guided relay outputs for machine control. OSSD Safety
outputs 1 and 2 are connected to the RM-1 and provide the power necessary to energize its relays. See
Figure 10-2
for the preferred connection method using the RM-1. The auxiliary non-safety output of
the MS4800 system can be used to signal light curtain status to a PLC.
