Schneider Electric TMZALM3LT Alarm Relay Module

Schneider Electric's TM2ALM3LT analog mixed I/O module for Modicon M238 logic controllers provides two thermocouple/low-level temperature inputs and a single output in a compact module, enabling precise temperature monitoring and integrated alarm signaling in industrial control panels. Two sensor inputs accept thermocouples or low-level temperature signals, while the remaining output offers a dedicated signal path for alarms or interlocks within the controller's I/O ecosystem. As part of the TM2 family, this module extends Modicon M238 systems with mixed analog I/O, delivering scalable, centralized temperature sensing for applications such as process monitoring, HVAC, and equipment protection. Designed for modular, scalable automation, it integrates with Schneider Electric's TM2 racks and complements other analog I/O and alarm modules to simplify wiring, improve diagnostics, and accelerate commissioning in temperature-sensitive workflows.
