SA801 220V AC 8 Wire
SA801 is an eight-wire, 220V AC ON/OFF actuator connection with potential-free feedback. The actuator opens and closes the valve and stays in its last position if power is removed.
Wiring Diagram
Supply and Earth Connections
Disconnect power before making or changing connections.
- Connect the red wire to 220V AC phase.
- Connect the black wire to 220V AC neutral.
- Keep these two supply wires connected during normal operation. Power is required for both opening and closing.
- Connect the blue wire to ground/earth.
Valve Control Connections
- Connect the green and yellow wires together to open the valve.
- Disconnect the green and yellow wires from each other to close the valve, while keeping the red and black supply wires powered.
- The green and yellow wires carry an internal low-level DC control signal. Keep their contact closed for as long as the valve needs to remain open. The internal motor stops at the fully open position.
Important: Do not apply an external power supply to the green or yellow wires. Doing so will damage the electrical board.
Potential-Free Feedback
- White wire: Feedback input/common.
- Orange wire: Feedback output when the valve is open.
- Brown wire: Feedback output when the valve is closed.
Frequently Asked Questions
Will the valve close if I join the green and yellow wires and disconnect power from red and black?
No. This is a stay-put connection. The valve requires power to both open and close and remains in its last position when the supply is removed.
Should I connect a power supply to the green wire?
No. Do not connect any external supply to the green or yellow wires; it will damage the electrical board.
