I'd like to connect an analog 4-20MA PH transmitter to a S7-1200 PLC. PH Transmitter - https://www.atlas-scientific.com/files/pH_transmitter.pdf What model of input card would work? I would assume a Siemens SM 1231 AI - 6ES7231-4HD32-0XB0 would work. Thank you! |

Hello, You didn't say us wich model of CPU you are using, however I presume that they don't have AI's embedded at your CPU (or the module present is already full). So, according to manual of your PH transmitter, probably SM1231 as you suggested, it wi'll be enough. I attached here the brief of the connections for current measuring of SM1231 module.
