Product Description
Pre-assembled module utilizes two included liquid sensors to provide control intended for "fill" or "drain" of a water tank. "Fill" mode energizes the relay when the lower sensor does not detect the presence of a liquid. The relay de-energizes when the top sensor then detects liquid. "Drain" mode energizes the relay when the top sensor detects the presence of liquid, and de-energizes when the lower sensor no longer detects liquid. Relay is SPDT with 5A contacts. Requires 12VDC, 50mA. Board dimensions 3" x 2.17" x 1.18". Note: This device is intended for use with water. Use with flammable or corrosive liquids could have hazardous results.
