Hello Yaya-Lzz; A PT 100 is a RTD (resistance temperature detector) and it produces mV signals corresponding to a resistance change de to the measured temperature. For more details, read the following articcle, but understamd that you cannot use a standard 0-10V analog input range in your PLC to read the RTD output: https://www.te.com/usa-en/industries/sensor-solutions/insights/understanding-rtds.html You have two choices, as I see it: - connect a 0-10V transmitter between the PT 100 and the S7-1200 analog input connections: - insert a PT 100 signal board (6ES7231-5PA30-0XB0) or a PT 100 signal module (6ES7231-5PD32-0XB0) in your S7-1200, these are designed to read signals from a PT 100. Hope this helps, Daniel Chartier |
