Built a single PID with two outputs 220VAC.

1/4" jacks for outputs to blankets?
Is that what I'm seeing?
whats the amperage rating of a 1/4" jack?

Over all a really clean build.
One day....

Yea, I was also concerned the first time I tried it. I have ran my highest amp mat for 4 hours (12amp), and the connections were barely warm. Im always looking for new methods for building stuff, when I find something thats works and looks better I'll try it for sure. Just having a cord hanging out the box works, but it just looks bad. I have an idea of what I want to try next I just have to find one that can handle 15amp.

One PID controller to control 2 heat pads.......with one TC? What am I missing here?

I know, I know! That's what the guy wanted, One PID, two SSR's, two mats, one thermocouple, 240VAC. I tried to get him to get another PID, but he didn't want to.

If I put one TC on the top cassette piece towards the tip or tail, the middle of the bottom heat pad would be 50-100 degrees different. They are going to have to figure out the perfect spot for that TC and then ramp super slowly. Not ideal.
