F3200 IS CIRCUIT USING 6-TERMINAL REPEATERS
Relay or Open Collector
For each AZC there must be either: a corresponding relay (e.g. Module Relay RLn) with
normally closed contacts breaking the supply to the Isolator as shown; or an open collector
output switching the supply 0V as shown. As the open collector is standard with an 8ZM it is
the cheapest alternative.
