The relay will go to the default state when the communication timer times out. Setting the timer value
to zero will cause the communication to never time out.
It is recommended to put a value in nci Max Send T to ensure the RIB re-synchronizes itself on the net-
work after power loss. It is the responsibility of the user to ensure this value does not cause conicts in
network trac. (No value = No “heartbeat” updates / no re-sychronization; Low Value = Many updates
but may cause many trac collisions; High value = Few updates but many less collisions.)

Notes:
• Order with P1 option by adding “-P1” to end of
model number. The P1 option is pre-programmed to
allow dry contact binary input to command the relay.
Contact closure on the BI will activate relay.
• When connecting 24 Vac to both the RIB(s) and a
half-wave device, damage to device can occur.
Option 1: Use separate transformers for each device.
Option 2: Add diode between devices, see Option 2
note below. ^^
