Hello, for measuring of a PTC you can use Analog input module SM 331; AI 8 x 13 Bit; (6ES7331-1KF02-0AB0) Then manual for this card can you find at this manual SIMATIC S7-300 S7-300 Module data There you can find the connection of the PTC also as a 2wire. (chapter 6.6). regards |

Greetings! Perhaps to begin with, tell me which PTC sensor you have? According to DIN 44081 they can be different. And as "CaOd" said, you need to read paragraph 6.6. (in manual Manual, 06/2017, A5E00105505-AJ) - this your module There is also no problem digitizing the signal in the controller itself -you can use various types of filtering and smoothing, both hardware and software (for example, take an analog signal processing unit from the library of PCS 7) AttachmentWiring 2-, 3- and 4-wire connection of resistance transducers or thermoresistors.PNG (334 Downloads) |
