FloJet Question

[Ghetto Wash]

Before IDX came out with the MX8, the only solutions I was able to find were a bank of relays or a multiplexer made by Car Wash Resources. I have these multiplexers on my equipment. I believe that they are still made, but If one ever goes bad I'll probably replace it with an MX8.

I believe CWR is MEP's former employer so he is probably familiar with them.

I would recommend the GinSan version over the IDX MX-8. It's nice to have the delay, but it's not really that big a deal. I've worked on a wash that had seven or eight IDX units, and after five years half of them had gone bad where the output would randomly not work. The GinSan GS-16D is a little easier to work with since you just get power from each solenoid or pair of solenoids and run a pair of wires to each of its inputs. When you combine all the "common" sides of your bays to use the IDX, you have to ensure that all the power is in phase or you may have issues elsewhere.

In the photo you quoted I used relays there because I was trying to find an electrical issue and I wanted to completely isolate the bays from one another electrically. The relays were a quick and cheap way to do that, and if I were building or remodeling a wash I'd use relays again. In fact I pulled a bunch of PLCs, relays, and a failing control system out of a wash and replaced it all with relays which saved probably $300 over multiplexers.





Another I did a few months later, had three boxes full of relays like this plus twice as many PLCs

Yes, and those multiplexers were made by Specialty Equipment Manufacturers, which has gone out of business. I have the part number for the Omron relay in it, but the unit itself isn't available. Car Wash Resources is also out of business.
