@Baron23 The e-nail you shared a photo of does indeed have a 5 pin XLR connector, If accurate temperature control is what you desire, check the specific components inside your e-nail control box and find the model number of the PID controller & whether there is a standalone SSR. You want an e-nail with a dedicated solid state relay, and a proportional integral derivative controller designed to output power to an SSR if accuracy with temperature control is desired.
Some e-nail builders use the EX variant of the Omron E5CC to simplify and save costs since you don't have to purchase or wire in a solid state relay. However the temperature control isn't going to be as accurate as an e-nail with a standalone SSR.
"There are 3 different types of e5cc. The RX that has just a mechanical relay output, The QX that has a DC out for controlling a SSR, and the CX(cant be used) which adjusts just a current output.
You can use either the RX like I did with no SSR by wiring AC HOT to PID pin1 and PID pin2 goes to AC HOT on the XLR. Neutral and Ground on the XLR go directly to the incoming AC.
Or you can use the QX if you have a compatible SSR (12V, 21mA max). PID pin1 is DC+ and pin2 is DC- to feed the input on the SSR.

"I use the "E5CC-RX2ASM-800" and it's worked reliably for 6 months so far with no SSR. The only thing about using the built in mech relay is keeping the temp stable, it likes to fluctuate about +-10deg, but not a big deal.
SSR versions are alot more steady, +-3deg."
