Schneider Electric TM2AMM3HT Analog Input Output Module

Schneider Electric TM2AMM3HT is an analog input/output module for the Modicon M238 logic controller, delivering two high-level analog inputs and one analog output in a single TM2-form factor card. The two input channels handle voltage or current signals, enabling direct connection to a range of analog sensors and transducers, while the single output channel provides an analog signal to drive a controller or actuator. As part of Schneider Electric's TM2 analog I/O family designed for the M238 platform, the TM2AMM3HT supports compact, scalable integration of analog signals in small to mid-size automation applications. This module helps consolidate sensing and actuation tasks on a single card, reducing wiring and simplifying topology within the PLC rack. Typical uses include process monitoring and control loops where a PLC reads sensor voltages or currents and returns an analog control signal to a valve, actuator, or signal conditioner. The TM2AMM3HT is designed to align with Schneider Electric's Modicon M238 ecosystem, offering reliable analog I/O with consistent engineering and maintenance practices across the TM2 module lineup. When selecting TM2 analog I/O, this 2-input/1-output variant suits applications needing moderate channel density with straightforward integration into existing M238 projects.
