Unlike basic temperature controller schematics that only cycle power elements, the WLX-896B integrates or interfaces directly with stepping motor drivers. This allows for automated physical adjustments—such as modulating mechanical valves, controlling conveyor belt speeds, or positioning automated dampeners based on thermal variables. The circuit paths utilize optocouplers to isolate high-current motor return paths from sensitive digital ground planes. Output Actuators (Relays and SSRs)
