The module handles -80 mV to +80 mV signals directly, with input resistance of 1 MΩ on all supported thermocouple types. ## Physical fit Common mode voltage is rated up to 120 V AC, with common mode rejection at least 120 dB at that voltage. Between the inputs and MANA (UCM) the isolation is 500 V AC.","metaTitle":"Siemens 6ES7231-7PF22-0XA0 8 AI Thermocouple, 62mm","metaDescription":"Siemens 6ES7231-7PF22-0XA0 analog input module for S7-1200, 8 thermocouple inputs (types E,J,K,N,R,S,T), bipolar ±27,648, 62 mm depth.
