Warrick 16DB1B0 Circuit Board R-410A the internal disc has likelyThe Warrick 16DB1B0 is a high performance Series 16D open circuit board designed for precise conductive liquid level control. This dual pole double throw (DPDT) control operates on 120VAC and is factory calibrated for 10K Ohm sensitivity, making it a standard choice for potable water, condensate return, and cooling tower applications. As a solid state liquid level relay, it utilizes the conductivity of the liquid to complete a low voltage circuit,
