Peter thanksfor that Anton I have the same fault on my boards The opticoupler lead you highlight is not connected back to -ve. by making this connection the board works Glad I found your review. Thanks

This PCB has mistake — one lead of optocoupler is not connected, so the device does not work. But it is easy to fix yourself. Also the specified parameters are wrong — when voltage will exceed 20 Volts, the MOSFET will break, because gate-to-source voltage of F5305S MOSFET cannot exceed 20 Volts. Also, if you want to control this board with 3.3 V logic, then you should short-circuit the LED, otherwise there will not be enough current for optocoupler. Also the module does not have protection diode to use it with inductive load.

Q: This relay don't pass current from k0 to k1 do u have any idea why? I have place positive of battery to +12v and negative to Gnd and 220v of fire exit to k0 and output of relay k1 to bulb and neutral of power to bulb. But still bulb doesn't glow the red light of relay is fine it show light when temperature is low and off when its's high

Peter K1 and K2 are the two poles of the relay switch. So there is no voltage supplied here. It's just a switch that connects to the external load that needs to be switched ( triggered by the change in temp). This is separate from the 12v that powers the unit.
