Parts under review / Digital PID Temperature Controller
Digital PID Temperature Controller
- A × B
- Panel cutout — the hole, not the bezel
- C
- Depth behind the panel, terminals included
Check the input type (thermocouple K or J, or Pt100) and the output type before ordering. A controller set for the wrong input reads a plausible but wrong temperature, which is the dangerous failure because nothing looks broken.

Supplied sample photos
Images supplied by the project owner. They illustrate samples only; confirm the exact part, dimensions, electrical details, and fitment before ordering.
Digital controller for ovens with a temperature readout. Pairs with a thermocouple probe.
Useful first checks. A PID controller reading wrong is usually a failed probe, not a failed controller. Check the thermocouple first — it is the cheaper part.
What this part is
An electronic controller that reads a thermocouple or RTD and drives a relay or solid-state output. Unlike a mechanical thermostat it anticipates overshoot, so chamber temperature holds closer to setpoint.
How it fails
Controller failure is blamed far more often than it actually happens. A wrong or drifting reading is much more likely to be the probe. When the controller itself does fail it is usually the output relay, which shows as a display reading correctly while nothing switches.
What decides whether a replacement fits
These are category-level selection factors, not specifications for a specific product. Confirm each value from the machine and the physical part.
| Parameter | Typical | Why it matters |
|---|---|---|
| Panel cutout | DIN sizes — 48×48, 72×72, 96×96 mm are the usual ones | The cutout, not the bezel, decides whether it drops into the existing hole. |
| Input type | Thermocouple types K or J, or Pt100 RTD | A controller set for the wrong input reads a plausible but wrong temperature — the dangerous failure, because nothing looks broken. |
| Supply voltage | Read the controller label and the machine supply specification. | Applying the wrong supply voltage can destroy the controller immediately. |
| Output type | Relay contact, or SSR drive voltage | An SSR-drive output cannot switch a contactor coil directly, and a relay output cannot drive an SSR. |
| Body depth | Behind-panel depth including terminals | Shallow control boxes leave no room, and the wiring still has to bend behind it. |
The mistake people actually make. Replacing the controller when the probe is at fault. Test the probe first — it is the cheaper part and the more likely one.

Fits these models
We have not published a verified model list for this part yet. We only list a machine once we have measured the part against it or a customer has confirmed the install — a list padded with guesses is worth less than no list.
Send us your nameplate and a photo of the old part and we will review what the evidence supports.
What to photograph and measure
Measure the panel cutout, not the bezel. Photograph the terminal block on the back — the wiring layout tells us the input and output type.
