SA301 wire connection is the basic connection for 12V DC Valve. 

sa301 12vdc 3 wire circuit

Details of the connections are as follows

  • Keep your 12 V 1.5Amps power supply ready or as per the instructions given in the actuator. Because the current rating requirements may differ from actuator to actuators.
  • Connect the 12V +ve to the Red colour wire.
  • Connect the 12V -ve to the Black colour wire. 
  • Connect the Green wire to the 12V +ve whenever the valve needs to be opened. 
  • This supply to the green wire can be given thru PLC, Relay Float switch.
  • As long as you need to open the valve, the green terminal should be connected to +ve 12V DC.
  • Note: Since the valve is stay put on power failure type. Red and black to be connected to positive and negative of 12V DC always.
  • Power consumption during valve close is zero and open is around 20mA. Actual power consumption takes during the movement of valve.
