Schneider Electric TM3TI8T Temperature Input Module

Schneider Electric TM3TI8T is an 8-channel temperature-input expansion module for Modicon TM3 controllers. With screw-terminal connections and a 24V DC supply, it provides eight analog temperature inputs that plug into the TM3 I/O bus. Each channel delivers 16-bit resolution in a single-ended configuration, designed to read temperatures from thermocouples and RTD/PTC sensors. The TM3TI8T supports multiple sensor types, including thermocouples K, J, T, N, E, R, S, B, and C, plus RTD/PTC options, with defined input ranges for each sensor type and a sample duration of approximately 100 milliseconds per enabled channel. This expansion module integrates with the broader TM3 analog I/O family to enable scalable temperature monitoring across industrial processes, HVAC applications, and equipment requiring multi-channel temperature sensing, and is available in the screw-terminal variant (TM3TI8T) as opposed to the TM3TI8TG spring-terminal version.
