Dedicated Analog Expansion Module for M238 Series:The TM2AMI2HT is a dedicated I/O expansion module for Schneider Electric’s Modicon M238 Logic Controllers, designed to extend analog input capabilities for high-precision acquisition of continuous signals such as temperature, pressure, and flow.
Dual-Channel High-Accuracy Analog Inputs:Features 2 analog input channels supporting multiple signal types including 0–10 V, 0–20 mA, and 4–20 mA, ideal for connecting various industrial sensors (e.g., temperature transmitters, pressure transducers), suitable for mid-to-high-end automation applications.
Direct Connection for Thermocouples & RTDs:Equipped with High Temperature (HT) measurement capability, it directly accepts RTDs such as Pt100, Pt1000, Ni1000 and Thermocouples (J, K, T, E, N, R, S types), eliminating the need for external transmitters, simplifying system design and reducing costs.
High Resolution & Measurement Accuracy:Utilizes a high-resolution ADC for precise temperature and analog signal measurement, with typical accuracy within ±0.5%, ensuring stable and reliable process control.
