The ±80 mV range covers all standard thermocouple outputs without scaling. Cold junction compensation is built in with ±1.5 °C accuracy. Diagnostic alarms, wire-break detection, and parameterizable channel configuration are standard. The module reports diagnostics via the S7-1200 backplane; readout is supported without additional hardware. Supply voltage monitoring and common-mode rejection (120 dB, min.) guard against noise and brownout. IP20; no enclosure sealing needed inside a panel. Approvals include CE, FM, and RCM (formerly C-TICK). The module carries a five-time drop test rating of 0.3 m in its package. Compliance documentation (CE declaration, FM certificate) is available on request. Parameterization is done in TIA Portal; the module is fully configurable (including input filter, wire-break response, and temperature units). The integrating measurement principle reduces noise on slow temperature signals.","metaTitle":"Siemens 6AG1231-5QF30-4XB0 SIPLUS S7-1200 AI 8xTC, -40..70°C","metaDescription":"Siemens 6AG1231-5QF30-4XB0 SIPLUS SM 1231 AI 8xTC thermocouple module. -40 to 70 °C, 8 inputs, types J,K,T,E,R,S,N,C,TXK.
