Specifications: Item Type: Water Level Controller Relay Material: PCB Application: Widely used in domestic water tower automatic water supply systems, automatic control of water pump motors and solenoid valves, aquarium feeding systems, automatic water supply systems for livestock farming, and other applications requiring automatic water supply and adjustment. Basic Parameters: AUTOMATIC CONTROL (AC 9-12V) Standby Current: 10mA Working Current: 40mA How to Use: Working Principle: Water level rises: When the water level is below the "low water level," the water pump starts supplying water to the water tower. When the water level is higher than the "high water level," the water pump stops supplying water. Water level drop: When the water level is below the "high water level," the water pump will not operate, and the water level will continue to drop. When the water level is below the "low water level," the water pump starts supplying water to the water tower. High: Upper limit probe; Out: Outlet probe; Low: Lower limit probe; In+: Power Terminal 1 (regardless of positive and negative poles); In-: Power Terminal 2 (regardless of positive and negative poles); NC: Normally closed contact relay; Com: Normally open contact relay; NO: Normally open contact relay. Package list: 1 x Water level controller relay
