Multiplexer or relays?

[Don B.]

They were having supply issues after COVID, and a lot of their products were very delayed. It could be a mistake on Sonny's end, but every IDX item except the AT411E vacuum timer shows out of stock on Kleen-Rite's site.

We’ll, looks like I’ll be staying with the relays. No one has the IDX multiplex controller, they said leadtime on it could be several months.
I can get all the relays I need! Easy decision now!

I have not tried these, someone on here said he did and he's had some failures, perhaps he put load through them but I would only use them to trigger another relay to take the load.

They're cheap and compact, and the relay element can be replaced for a couple dollars if it fails. They would go along well with this relay.

Multifunction timer relay Selec 600XU-A-1-CU

Multifunction timer relays, 13 time functions, 10 time ranges, 20-240 V AC/12-240 V DC Supply Voltage, Contact rating 5A@ 250 V AC, Front Knobs for Setting the Time Range/Scale/Mode, Slim…

Edit: Here's something on the same site as the time delay relay, looks promising and also very affordable:

Thanks, I’ve always used the Omron cube relay, Just a basic 24 V, normally open, latching relay. They’re not very expensive and I rarely ever change one!

We have used the ginsan GS16 D, my old favorite for larger sites with 12 inputs. The new version doesn’t have more inputs than the IDX, tho . I have had good luck with the IDX. We had one go out recently when we had a big water leak, but it did not get wet tho must of been humidity. If you are wiling to do all the wiring I would do relays. They are indestructible.

That's a good relay, a bit overkill for just isolating voltage and not at all compact. I like the DIN style because I can wire them sitting at a desk and just snap the whole array onto the rail. I used to use this one along with the base, but they've gotten too expensive so I've been considering different ones for the next project.

I forgot about that one, IMO it's a better unit than the IDX. I don't think I've ever replaced a bad one.

I’ll probably just stay with the relays. I don’t mind wiring them, I’ve done it before.

Another plus of those automation direct ones, and probably other din style relays, is the jumper bars, so you don't need a thousand small pieces of wire when wiring up a relay bank

I need to remember to use those on my next project. It sure would make things easy to sit down and bridge them all together. The last couple times I rewired a wash I had to cut and strip about a hundred short pieces of wire to jumper them.

 

[Don B.]

Those jumper bars would be a good idea. I’d probably do something like that but I’ve already got the jumper wire harnesses with the crimp style plug-in spades on them . I’ll just pull them off the old relays, check all the crimps on them, and just reuse the wires.
