Board for control wiring

My own system for boiler involves 4 zone valves, 3 manifolds for infloor tubing, indirect water heater tank, and 2 air handlers/AC...all run by 6 tstats...and probably more that I can't think of right now.
I use pvc "wiremold" type channel typically used in large control panels. It is about 2" x 1/2" with snap on cover. The sides are slotted for wire entry, low voltage cables jump in and out of it as needed. Most of the ungraceful wire splices are within this channel. There is 8 linear feet on the wall with 2 4' risers to the ceiling. The cover has labeling surfaces as needed.
You could have 24 volt led pilots poking up thru the slots.

Any 120 vac is mounted above it in steel boxes connected together by conduit.

Hey @ethicalpaul try digi-key electronics online. Or any equivalent company for that matter should be of some help.
To bad there are no more radio shacks in town. They would of had all of what you are looking for.

i use terminal blocks like these for low voltage applications:



not sure i would leave it out in the open if you are making AC connections.. i think some snap on plastic covers are available.
or, i suppose if it lived inside a junction box it would be ok

Those are some permutation of a phoenix connector. you can put more than one wire in a terminal depending on the size of the terminal and the size of the wire. there may be a version of those with terminal blocs that unplug, that is a lot more convenient to wire. that style of terminal in a pluggable block is what most professional AV equipment uses now.

I second @SuperJ. I don't know that you need a "board" per se. A good terminal strip will suffice. I use color coded Dinkle terminal blocks, Also, a good technique is to put a junction box outside your boiler and/or control panel to accept all the low voltage wires from different sources (i.e., out door reset, any system temp probe and boiler and DHW end switch wires


) then exit the junction box to the boiler and/or control box with just one 18-8 or 18-6 thermostat wire to reduce all the clutter going into the boiler and the control box.

Thanks all, I wasn't aware of DIN rails before, I'll learn about those!

@Intplm. I'm very familiar with digi-key, having a lot more experience with digital and analog electronic circuits than with industrial control circuitry. What product in particular were you thinking of from their massive catalog?

I didn't have a specific product in mind. However they have a massive selection and thought they would have something that would suit your needs. You can almost find anything from them.

Sounds to me like you will be making your own board. Some folks that I have worked with will use a electrical box or electrical panel with a door of some sort that will fit there components. I like the terminals from amazon that you posted.
