The Schneider Electric TM3TI8TG is an analog input expansion module in the Modicon TM3 distributed I/O system designed for use with compatible logic controllers such as Modicon M221, M241, M251, and M262. It provides 8 high‑resolution analog input channels capable of measuring temperature and resistance‑based sensor signals — including thermocouples, thermistors, and resistive sensors — making it ideal for temperature monitoring and process feedback in automation systems.
