The Plant Circuit controller is a versatile and cost efficient controller intended for centralised control up to 25 refrigeration devices (or circuits).
The controller has the ability to operate Liquid Line Valves, Fans, Trim Heaters, Lights, Defrost relays, Remote relays, and Stepper Motors. The Plant circuit controller also provides monitoring and alarm functionality.
Up to 10 Expansion Boards can be connected to the Main Board to increase the available inputs/outputs.
