How to wire a temperature patrol detector
Thread Content
Excuse me, after connecting the wires of the 12-channel temperature monitoring device, 11 of them show HH while only one shows a normal value. What’s going on?

And if all the division values are correct, then the wires aren’t connected properly. . For each temperature point of the inspector, one wire is connected to the inspector separately, while the other wires are all connected in parallel to the designated terminals of the inspector; it depends on the wiring diagram to determine which terminals these are. What is referred to here is the two-wire connection method for thermal resistors. It would be best if the original poster could provide pictures of the front, back, and the label
I’d like to ask what a temperature monitoring device is used for
The wiring is incorrect; read the instruction manual carefully and wire it according to the instructions.
It’s actually a multi-channel temperature controller. .
Thank you. It’s fixed; I made a mistake back then – the wires were connected in reverse: funk:
Thank you, I got up in the middle of the night to pee and suddenly remembered. I connected the wires in reverse
