Hi, i have some problem with analog module, i attachment de pictures of the problem. I am occupying a type J thermocouple, and i read a bad temperature. I read that in this module i do not need scaling with FC105, only connect, configure and read in °C. But with 20°[C] room temperature read in PIW 514 -58. i changed thermocouple position and i have the same problem. Please, anybody help me?.

I tried connecting a PT100 to channel 0, and connected thermocouple to channel 2. I get the status value 32767.

Hello, First of all i see no wires going to L+ and M to supply the card. The PT100 must be conected to channel 0 and 1 (4 wire) If you have 2 wire sensor you must bridge 6 to 11 and 7 to 12. See attached document. Regards, Marcjan Attachmentwiring1KF10.pdf (436 Downloads) |

Agree, first of all you should make RTD sensor work. L+ and M required of course. |
