The Schneider Electric TM2ALM3LT is a Modicon TM series analog input/output expansion module designed for compact PLC systems requiring mixed signal processing. It is used in industrial automation applications where both analog measurement and control signals are needed in a single module.
This module is part of the Modicon M238 / TM platform, and is commonly used in small to mid-scale machines such as HVAC systems, packaging equipment, and process control units. It supports temperature measurement (thermocouple and RTD) as well as analog voltage/current signals, making it a flexible solution for multi-sensor environments.
