The Discrete units provide M12 or M18 connectors for ease of
installation. The circuit includes the Air Economizing Function
and PNP (Sourcing) Outputs.
No external PLC programming
is required for Air Economizing Functions because this func-
tion is built into the electrical unit.
The following are the Pin
