NODE – USING DC LATCHING SOLENOIDS WITH BATTERY CONTROLLERS
A battery-operated controller sends a quick DC pulse to operate the solenoid, therefore the battery-operated controller requires a DC latching solenoid to operate correctly. Also, the DC latching solenoid will have one black wire for the common wire and one red wire for the station wire. It is important that the wires are connected correctly for proper operation. Black connected to the C or COM (common) terminal inside the controller, and the red wire connected to the appropriate station terminal.
