SA501 wiring connection is a 12V DC with feedback function.

sa501 12vdc 5 wire circuit with feedback

Details of the connections are as follows

Keep your 12V 1.5Amps power supply ready.
Connect the 12V DC +ve to the Red colour wire.
Connect the 12V DC -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.
Feedback output can be taken from blue for open side and yellow for close side. Feedback voltage is +12V DC

How to connect a switch.

A switch is a simple device that is used to turn an electrical circuit on or off. Here are the basic steps for using a switch:

Make sure the power is off: Before working with any electrical device, it is important to ensure that the power is off. This can be done by turning off the circuit breaker or removing the fuse that controls the circuit.
Connect the switch to the circuit: The switch will have two or more terminals that are designed to be connected to the circuit. These terminals are typically labeled as “common” and “normally open” or “normally closed”. The specific configuration will depend on the type of switch you are using.
Wire the circuit to the switch: The wires from the circuit should be connected to the appropriate terminals on the switch. The wires can be attached by either wrapping them around the terminal screws or inserting them into the appropriate connectors.
Turn on the power: Once the switch is connected to the circuit, you can turn the power back on. This will allow you to test the switch to make sure it is working properly.
Test the switch: To test the switch, simply toggle it on and off. If the switch is working properly, it should turn the circuit on when it is in the “on” position and turn it off when it is in the “off” position.

Remember that working with electricity can be dangerous, so always exercise caution and follow all relevant safety guidelines when working with electrical devices. If you are unsure about how to use a switch or any other electrical device, it is always best to consult a qualified electrician.

Public restrooms are evolving, thanks to advancements in technology that prioritize hygiene, efficiency, and sustainability. At the forefront of this transformation are sensor urinal flushers, which are revolutionizing the way we interact with restroom facilities. These touchless devices not only reduce the spread of germs but also significantly cut down on water waste, making them a key player in the future of public restrooms.

UPVC Motorized Ball Valves are available in Socket Ends (pasting type) and True union ends.

110V DC and 220V DC Motorized Valves (Ball and Butterfly Valves) are used in thermal and hydro power plants. The valve are operated with auxiliary battery power pack of the power stations.

Multiple tank water level controller is a system of filling water from the borewell or sump to the multiple overhead tanks. Motorized Valve with Level sensors in tank is used.
