Schneider Electric TM3AI8 Analog Input Module

The Schneider Electric TM3AI8 is an 8-channel analog input expansion module for the Modicon TM3 PLC family, featuring screw-terminal connections and a 24 V DC supply. Each channel provides 12‑bit resolution and can accept both voltage inputs in the range of -10 to +10 V and current inputs in the 0/4‑20 mA range, enabling flexible sensor interfacing in industrial environments. The TM3AI8 is available in two terminal variants: TM3AI8 with screw terminals and TM3AI8G with spring terminals, both designed to plug into the TM3 I/O bus for scalable automation. As a TM3 expansion module, it supports integration with Schneider Electric automation platforms for process monitoring and control in applications such as manufacturing lines, energy management, and HVAC systems.
