5.2.2 Quad Relay Card Rear Access Connections
RL1-NC (Master Fault) 1 2 RL1-NO (Master Fault)
1. NC = Normally Closed. NO = Normally Open. COM = Common.
2. Relay contact conditions refer to the no power state of the relay.
3. The functions shown for terminals 1 to 12 are the default functions for
relays RL1 to RL4 only. For other congurations - refer to the conguration
printout.
