Hi SlotracerM,

There are three options:

First simply to use the screw terminals which are fitted as standard and connect a 3-wire cable which has an RJ12 plug at one end (I will share a wiring diagram).

Second is to use the RJ12 printed circuit board which can be fitted onto the screw terminals of the opto module using 90 degree header pins. This reduces the risk of cable strain.

Third is to use the RJ12 printed circuit board as replacement for the standard screw terminal block. This is my preferred approach as per photos earlier in this thread and again it minimises the risk of cable strain.

I have plenty of the small printed circuit boards (PCBs) so please send me a private message using this forum if you would like me to pop one in the post for you.

While I remember - I will follow on with some wiring photos/diagrams. There are only three wires so it’s absolutely straight forward.
