Digital Inputs and Digital Outputs
All digital inputs and outputs are predefined and governed by the electrical wiring diagram. All
settings are pre-configured at the factory prior to shipping. Changes are not recommended
unless suggested by the factory. Consult the factory for more detail.
In general, the controller works with a 24VAC input from the normally opened relay. The
internal relay from the controller sends out a 24VAC on the digital output terminals to
designated coils in order to energize the high voltage components.
