12V relay module, optical isolation (5V-24V or 0V acivation)

Simple relay module that can be used where you have a low-voltage-signal, that has to turn on or off a higher voltage.

With the jumper you can decide if you want the relay to activate when it receives a voltage, or when the signal is low (ground 0V).

The relay can connect or disconnect max 250V AC or 30V DC, max 10A.

The relay on the module is 12V, so you will have to connect 12V to DC+ and DC-.

There is no connections to the switches in the relay, so you will have to connect voltage on eg. COM, and connect the powered unit to NO or NC.
