If you are using this as part of a gate or door opening system there should be auxiliary power source terminals on the control board usually 24 volts . If that isn’t available you can use a 24 volt transformer to power it . The unit works on ac or dc voltage .

When the beam is broken, the circuit closes. Does it close only for time the beam is broken or is there an added few seconds before the circuit opens?

It’s only for the time interrupted and continues if the beam is interrupted. Since mine is controlling a gate, the gate circuit board tells the control what to do next either reverse to fully open for a few seconds or keep closing.

I need to see simple wiring diagram so I know whether to buy it or not I need three of them and I need to order it immediately?.

Can you contact the seller directly to get a wiring diagram ?
