TM3AI8G

The Schneider Electric TM3AI8G is an 8-channel, high-precision analog input module from the Modicon TM3 distributed I/O system. This module is designed for versatile signal acquisition, supporting multiple input types including voltage, current, thermocouple (T/C), and resistance temperature detector (RTD) signals. It features channel-to-channel isolation for enhanced noise immunity and is ideal for process monitoring applications requiring measurement of diverse analog signals.
