The Schneider Electric TM2AMI2HTN is a Modicon TM series analog input expansion module designed for compact PLC systems requiring reliable acquisition of analog and temperature signals. It is widely used in OEM machines and small automation systems where accurate measurement of process variables such as temperature, voltage, and current is required.
This module is part of the Modicon M238 / TM expansion ecosystem, and is especially designed for simplified wiring, stable signal conversion, and cost-effective integration in machine-level control applications.
Compared with standard TM2 analog modules, the “HTN” variant is optimized for direct integration without additional adapter modules, making installation faster and more compact in control cabinets.
