I'm confused by the oem relay on an Italian ISA Samoa gelato cooler.

The cooler is 30 miles away, so I cannot go look at it until next week. Would like to order replacement relay now.

The cooler was built for operation in USA. The controller is Eliwell ID974, 115v version.

The Eliwell controller has an onboard 115v to 12v transformer. It doesn't say whether the 12v is ac or dc.

The next photo shows a partial view of the relay. The model is G7L-2A-TUB.

I think they used the same 240v relay in all the coolers, and just allowed USA 120v power to be switched by the 240v rated relay.

But I'm confused by the photo. It seems to say that the coil voltage is 200-240v. Am I reading that correctly?

I expected this relay to be driven by 12v to switch 120/240v, and was ready to order on Mouser until I saw the photo.

Then I looked on Mouser and saw that the relay is available with specs for coil voltage of 12vac, 12vdc, and even 200-240vac, to switch either 120vac or 240vac.

Then my brain began to smoke.

Hoping to tap into knowledge here.

On an Italian cooler with Eliwell ID974 controller, does the controller's transformer output 12vac or 12vdc?

Is the coil in the big relay driven by 12v or line voltage?

Can anyone identify the replacement relay I need to buy based on the photo and the info I've given about the machine?

If the oem relay in the photo is actually driven by 200-240vac, how crazy is it that it was working in a 120vac system?

Thanks for any help you can offer.

My plan:
Buy replacement controller, probes, and relay;
then travel over to cooler location and replace all these parts;
then see if it runs.

Long-distance jobs like this can be quite frustrating.

Thx.
