Oh and BTW the controller I use the Payne 18TB 2-25 is rated for constant resistive loads. But it works?????

Ok, I have one on the way and will give it a try.

Relay came in the mail today, soon as I can give it a try I'll let everyone know the outcome . . .

cool!! I dont see why they wont work ???

This is advertised as an SCR controller, but if you read the fine print it is actually a Triac controller.
That is why they say suitable for resistive loads only.
Yes it will work, but can be prone to erratic operation under some conditions with an inductive load.
If it does occasionally misfire, you probably will not know, except the test pressure may be a bit unsteady or suddenly change.

Thats why I talked with Roger at Payne he said send both of my Payne 18TB -2-25 back & would make the changes to the controllers so they would not have
a erratic operation & he also said if I tryed to use them as they were if I would turn the pot controllers to fast it would fry the fuse. That how do you wire them
to get two 120 volt legs out of them ??

You cannot.
One controller can only control one (two wire) load, at either 110 volts or 220 volts.

That is what Roger told me & Neil Baer A Electrical engineer told me to.

I've been using a Payne 18TBP-2-15 to control two motors for two years now. I've had to replace the fuse once. Haven't noticed any problems with this setup.

When I looked your controller up in the spec reads its a 240 or 220
how did you wire it up to get two 110 vacuum motors to run off of
one controller No Pun intended Ray The Payne controllers is keeping
from finishing my wiring for my flow bench. Here is the link to my flow bench
