M122 - setup example

Connection plan for 12 V load, without external power source.

Clarification: There is no voltage at the output of the module!. It is just a switch.
Some customers write that they have connected a lamp at the output and that it does not switch on. The M122 Twilight Switch is operated at 12 V DC, but other voltages (e.g. 24 V in a ship) can be switched with the built-in changeover switch. The changeover switch has no electrical connection to the 12 V supply voltage of the module. But because customers also like to connect a 12 V lamp and do not know how to connect it with the 12 V voltage, we have sketched a connecting diagram for this application here. But you may also buy our Twilight Switch M197, which has no built-in changeover switch and directly emits a voltage for the operation of a lamp.
