The A-165 is the right module. But you will have to modify the corresponding
input of the A-165 a bit: add a pull-up resistor (about 100k) to +12V
because S-Trig switches to GND and you need a positive voltage while the
S-Trig is open. We have a document available that descibes the corresponding
modification of the A-165:

If you order a new A-165 we can add the mod to one of the inputs for free.
