Wait a minute here......like an optical coupler. Signal in signal out isolated?

Ya, they are optically isolated solid state relays (SPST) used on Traflomatic & TAC50 controllers. The input modules are 24vdc or 120vac and switch 5 vdc to the CPU. The output modules have 5 vdc coils and switch contacts for either AC or DC. So I think it's just the 4 modules we would need it to test, if there are more I'm sure someone will correct me.

Thanks, Do they plug in or hard wired?

So far we have

Schrack RTE24615
Omron G5RL-1-E-AC120
Finder PN- Type 44.52 /6amp, 250volt
Schrack PN-SR2M-V23047-A1024-A501 6amp,250volt
PMIs
Yellow Jackets could do both 2PDT & 1PDT
12-24-48-120 AC/DC?
With the different voltages involved, have to use house power

Anything else?

Jim

Jim,
May I suggest a way to run leads to test relays such as the CA series...

Ideas?

Ya I've never seen a socket for them exactly. You may have to cannibalize a PMI card, they used individual pin sockets set into the circuit board.

With the Yellow Jacket relays, It would be nice to be able to test the 4 Poles too that MCE used on the HC-ACI board. The part # should be DS4E-M-DC48V

I think the leads would be a good idea too. Even if you just put jacks in so the leads wouldn't be in the way if you weren't using them. Maybe provide for the coil and 1 or 2 poles.

Got It, good thing about Yellow Jackets they fit in an IC socket

Good Morning All,

When you say test leads. Will they supply 12-24-48-110 ac/ac or the above plus leads to test contacts?

Sorry for not responding earlier to your email. I'm a little overwhelmed right now.

Yes, if there were ports, plugs or a terminal strip for leads a larger relay could be tested on the controller.

We had a car that would run for hours without fail. But after so many hours, the car overload would trip when the brake failed to lift. Everything would ring out fine on the brake relay. I didn't want to just bang the car on and off. So, With one of your earlier version of the Wizbang tester. I made a plugin base with leads to test the brake relay on a MCE VFMC 1000. Sure enough after cycling the relay on and off many time it would fail.
Let me know what you think or just take my idea and include some modified male pugs as part of your unit...

Yeah, can do it. So you just want test leads that will only test a set of contacts?

Will the contacts be isolated from the controllers power supply. The way it would work 3 test leads NO-COM_NC in order to these them it would be necessary to run 12 VDC to the common and back out to the tester.

Yeah?

QUESTION,

WHAT IS THE VOLTAGE FOR THE INPUTS & OUTPUTS FOR THE PMIs?
