Schneider Electric TM3TI4 Analog Input Module

Product Description

The Schneider Electric TM3TI4 is a high-performance analog input module designed for Modicon M221, M241, M251, and M262 logic controllers. It provides four flexible temperature and voltage/current inputs with 16-bit and 15-bit + sign resolution, enabling precise acquisition for industrial automation applications. Its compact design, intuitive assembly, and seamless integration with EcoStruxure Machine Expert software make installation and configuration fast and efficient.

This module supports a broad range of analog signals, including thermocouples, RTDs (Pt100/Pt1000, Ni100/Ni1000), and standard voltage/current inputs. Moreover, it ensures reliable operation with high isolation between inputs, internal logic, and supply, making it ideal for demanding industrial environments. With its IP20 rating, rugged screw terminals, and compact footprint, the TM3TI4 expands the capabilities of Modicon controllers while maintaining flexibility and reliability.
