Sorry for bothering again,
I am from Chile and electricity here is 220V.
Also, I am nothing goot at electrics.
I want to know if the artefacts I am buying are going to work with my heat blanket and with the 220v electricity that Chile has.
The PID and SSR will be fine. Both are rated for 220V power, and the SSR handles up to 25A which should be fine for a blanket if not two blankets.
The contactor looks also to be rated for 240V and 40A - but I didn't use a contactor in my setup so don't know that much about them.
Looking at the diagram the SSR is wired wrong and as stated above you don't need the contactor. The PID only controls the DC side of the SSR, the output or AC side is only controling one leg of the AC voltage the "hot" side of it. The other leg or the ground goes back to the PID and never to the SSR. Think of the SSR as a light switch that is controled by the PID.
I think the SSR is wired properly, he just has it labeled a bit oddly.
IN is the low volt control side.
Out is the power circuit.
If you look closely the neutral runs through the contactor to the blanket and the hot goes through the contactor, the ssr, the fuse, and to the blanket.
I think the contactor is there, because of an assumption that the heater switch can't handle the load of the blanket.
Depending on the switch that may be the case.
Looks fine as is, assuming that the SSR is just labeled funky.
