you have everything needed to make it run, you might need a project box or something to spruce it up a bit.

That’s how I read the schematic too. With regard to amp load capabilities on the PID without an SSR, most likely in milliamps.

OP should insure the SSR is mounted on a surface that will dissipate the heat from its metal backing.

I would fuse the load side on the SSR. We discovered that a dead short on them causes them to explode.

it just cracks the ceramic or literally explodes?

It exploded with a loud bang about like a Blackcat and blew the unsecured cabinet door open

Hee, hee, hee, we did a second 25A SSR just for shits and giggles.

We moved on to oxy/fuel in a garbage bag with a cannon fuse attached to the outside, and attached to another garbage bag full of helium for a 4th of July salute one year and it didn’t rise as fast as predicted, blowing out a lot of windows in our waterfront ship repair site.

A lot of wild and crazy guys in the metal trades union, many of whom survived.

Since we’re talking explosions…
I once took a deli container (the medium size ones you get potato salad in), and proceeded to fill it with gun powder. I laid a layer of hot glue across the top with a wick inserted directly in the middle. (I was 14 at the time) I taped it to a palm tree on the beach, and lit the fucker…
Well, my dad was on the other side of the island, about 2 miles away. He told me when he heard the blast he knew it was me. I set off almost every building and car alarm within a 1 miles radius, blew the palm tree in two, and blew out like 9 windows in our neighborhood.

Boy did I get my ass beat for that! BUT it was fucking worth, and I’d do it again!

Anyone care to explain what a lot of the electrical terminology he is using means?

Will I need any wire to connect the SSR/module to my PID? Or do I use my thermocoupler?

Hi,
You will defiantly need some lengths of wire to do this. your t/c should have wires already that you can connect to the back of the pid.

What terms? Google is a great resource.

Yes my thermocoupler has a red and blue tipped wire. My heat pad/heat wire doesn’t though but thats the final step. What kind of wire should I get?

36

So the red and blue wire from the t/c go to terminals 3 and 4

Are you looking to control the heat pad with the pid? What type of current are you throwing at it? volts amps?

Project box like a metal box? I’ll get something after I get it working if I do. My t/c, red wire and blue wire connect to which one, 3 or 4?

38

Yes I want to control temp on heat pads. And it says “Power: AC100-240v”

you should be able to go either way with the red/blue wires, if it dosent work you could swap them.

Ok. Attach thermocoup, stuck on how I attach SSR To the Pid, but my guess is grab some more wire?
