Figure 2-26: Wet and Dry Contact Input Wiring Examples
The locations of the output relays have a fixed assignment for the platform called the
master identifier. I/O options that include inputs occupy the fixed assigned output
locations so in these cases the relay assignment maps to the master identifier.
The critical failure output relay is reserved as Relay_8 and it is omitted and is not
programmable.
