SA501 12V DC 5 Wire
SA501 is a five-wire, 12V DC connection for motorized valve actuators with open and closed position feedback. Prepare a 12V DC, 1.5A power supply for the connection described below.
Wiring Diagram
Wire Connections
Disconnect power before making or changing connections.
- Connect 12V DC positive (+) to the red wire.
- Connect 12V DC negative (−) to the black wire.
- Keep the red and black wires connected to the positive and negative supply terminals during normal operation.
- Connect the green wire to positive 12V DC whenever the valve needs to be open.
- The green-wire supply can be switched through a PLC, relay or float switch. Keep it connected to positive 12V DC for as long as the valve needs to remain open.
Feedback Outputs
- Blue wire: Open-position feedback.
- Yellow wire: Closed-position feedback.
The feedback output voltage is +12V DC.
Power Failure and Consumption
The valve is a stay-put type on power failure: it remains in its last position when power is lost.
The supplied guide states that consumption is zero when closed and approximately 20mA when open. The main operating power is consumed while the valve is moving.
How to Connect a Switch
A switch turns an electrical circuit on or off.
- Turn off the power. Isolate the circuit using the circuit breaker or fuse controlling it before working on the connections.
- Identify the switch terminals. Depending on the switch, these may be labelled common, normally open or normally closed. Check the configuration of the switch being used.
- Connect the circuit wires to the appropriate terminals, using the terminal screws or connectors provided.
- Restore power after completing the connections.
- Test the switch by toggling it on and off to confirm that it switches the circuit as intended.
Safety: Follow the relevant electrical safety guidelines. Consult a qualified electrician if you are unsure about connecting the switch or any other electrical device.
