PID Temperature Controller Industrial Automation Control Meter Indicator, Jaybva High Voltage 100V to 240V PID Thermostat with K Thermocouple 25A SSR Fahrenheit and C Display Alarm Output TC RTD Input

Works great! Used in a product validation test for running a thermostatic heater.

Great controller. Comes with SSR relay and Type-K thermocouple so you only have to add a heating device. Instructions are technical and sparse but start with auto-tune mode.

I bought this to get an accurate read on the temp of my kiln. My kiln can with a dial so on medium it is about 1500 degrees. Doing enamel jewelry and paintings I need a more precise read. The thermostat that came with this is not made for such high temperatures. Solve that by using the original thermostat and hooking it up to the digital box. Now I can set the temperatures I need for each type of enamel I use. Very inexpensive way to do this.

It works.The only thing I could ask for is another page of instructions explaining the software setup in a little more detail. For example, the pulse width modulation period is fast, about 1 second. This is good in systems with an electrical resistance heater controlled by the included solid-state relay. But other loads, like a motor, might do better with slower switching. Geeky software details like that are not explained in the 2 pages of instructions, which are attached.This is a great value for $30.

It does exactly what it's supposed to. My only grip is with the mounting and hardware. Buyer should notice that this one (25A) does not come with heat sink for SSR or the screws for mounting it. The piece that holds the PID in place isn't the best but it still works well enough. You have to be very precise in cutting the square hole. Absolute zero room for over cutting.

easy to wire and program for heating and accurate control

The unit is too difficult to setup due to the complexity of the instructions.

instruction translation not great. unit preset to low temp. once we figured it out, it appears to work fine.
