Contact board as terminal for PLC FATEK and UTP 5e cables - 24V, 0.1A/0.8A

1. Is the contact board suitable for use as a terminal for cables connecting the inputs on the PLC (FATEK) to cables (UTP 5e) connected to the bell switches operating the on/off lights in the house? Voltage 24V, current rather less than 0.1 amp. There would be goldpins crimped on the ends of the wires.
2. as above, only connections made between PLC outputs and relays, where the current at 24V can reach up to 0.8A.

The contact plate is a bit of a precarious solution.

I have some concerns too, only actually what would this uncertainty consist of? The solution is practical in that it offers the possibility of packing a large number of connections very densely, which is hardly satisfactory and expensive with other solutions (e.g. so-called Zugi).

I also thought about using LSA connectors (commonly called Kron connectors), but there it is impossible to splice three wires together, the connections are not very clear and inconvenient if you have to rewire something.

Purchase a universal board in this case and solder the golpin sockets on

I have thought about this too, only the solution is not very aesthetically pleasing and more labour intensive. I'm looking for arguments for and against for now. If branded terminals work on the principle of spring-loaded pressure plates, why wouldn't the same principle work for contact plates?

Use connectors with a grid of 3.5 or 5 mm soldered to the universal plates.
They can be detachable (screw or spring-loaded)
A bit of effort in preparing the terminals, and then....bajka

I would have no objections to such a solution, especially as it is used by someone with experience in the field, I already know how to pack the connections densely enough, but the question - whether the contact plate is suitable for use as a terminal - remains open.

I have now checked the connection in my contact board out of curiosity, and I will say that the goldpins sit quite firmly. I think this could work well. I would still tie the wires together.

I ended up plugging twisted pair cables from the bell buttons into the patchpanel in the intermediate distribution boxes.


Route everything via multicore cables e.g. 4x50x0.6 to the central rack - there the cables are routed out to the patchpanel and connected via patchcord to the PLC


Patchcord cut in half and connectors made on the cut end.
Connectors plugged into PLC.


I have dispensed with the contact board as the above solution seems clearer and easier to test or measure wiring parameters.

In this post about something completely different I uploaded a pic of the tiles I use for this purpose.
In the photo you have the end to the box. In the switchboard, however, there are larger boards with 8 RJtles that fit into the base of the Z100 enclosure
The small one has an LED to indicate the presence of power and the large one has connections made so that I have power on each port. Only one cable goes to the board.
