I have built and sold around 35 relay testers that test relays found on older equipment. I have another model that tests big relays found on a lot of older independents up to 220 VAC
I have be out of it for 16 years now so I watch this site with keen interest. Gotta tell you it's a whole new ball game.
I hear a lot of chatter regarding relay failures on the newer stuff.
I would like to build another tester centered on the newer stuff which would be smaller and lighter.
Need some help from you guys, need to know just what relays and what voltages need to be incorporated in my new project.
Thanks in advance for your help in keeping a old elevator man out of the Local Beer Joint.

Do both of these relays use the same base? If so I do have them covered on the current model.
Thanks Again,
Jim
The Thyssen TAC20, 20-03, TAC50-04... They use these problematic 24volt relays by Fender, and Schrack (blue and brown respectively). They're a pain when a simple problem occurs. SPDT 24VDC. Then the almighty MUTS relay is 120 volts AC, and a few 110 VDC. All are SPDT. I think I have those correctly identified, and I believe they're all the same base, someone will correct me if I'm wrong.
If you need part numbers, they'll have to show later.
Both Finder and Schrack relays are DPDT. The voltages mentioned above are correct though.
Finder PN- Type 44.52 /6amp, 250volt
Schrack PN-SR2M-V23047-A1024-A501 6amp,250volt
The OEM blue plastic encapsulated ones are the worst.
So far the all of the above will test in the original WizBang.
Would it be worth building something that will test these guys?
By the sound of it you guys probably have spares in your pocket.
Please keep up the input,
Jim
Thyssen does sell a little tester for the 24 volt relays only. It has one blue Finder base and one black Schrack base.
I have these covered, my tester plugs into the wall.
Don't think I can compete with this one.

What about PMI modules? Or the miniature Yellow Jacket relays DPDT in 12, 24, & 48 vdc?
As far as the yellow jackets, adapter socket would do the trick.
Gotta ask, been on the couch for 16 years now , what is a PMI module.
DAH...............
