The CCC Neptronic Relay Interface Board provides a reliable interface between low-voltage control systems and line-voltage HVAC equipment. By isolating control signals through relay contacts, the interface board allows thermostats and digital controllers to safely operate high-voltage loads.

Commonly used in fan coil and equipment control applications, the board enables HVAC professionals to integrate digital room controllers with heating elements, fan motors, and other high-voltage devices.

Available with multiple relay outputs, the board supports flexible HVAC control configurations while maintaining safe electrical isolation between control circuits and equipment loads.
