The output contact assigned to ‘Relay OK’ signal remains in active state when the relay is Healthy, i.e.
NO contact will be in closed position and vice versa.
The output contact assigned to ‘Relay OK’ will become inactive in case any error is detected / failure
of auxiliary supply.
There are 4 nos. of programmable binary outputs (2 NO + 2 C/O) marked as RL1 to RL4. Any binary
output can be used as watchdog contact by assigning ‘Relay OK’ signal through ‘IO
CONFIGURATION’ setting or using ‘IO Mask’ function in P50 Agile Configurator.
