Schneider TM3AI4 Analog Input Module 4 Channels 24V DC Screw

Overview
The Schneider Electric TM3AI4 is a high-precision analog input module from the Modicon TM3 expansion range, designed to enhance the analog input capabilities of Modicon M221, M241, M251, and M262 logic controllers. Featuring 4 fully configurable analog input channels with 12-bit resolution (11 bits + sign effective), this module provides accurate measurement of voltage or current signals from a wide range of field devices. Each channel supports multiple input types including 0…10 V, -10…+10 V, 0…20 mA, and 4…20 mA, making the TM3AI4 ideal for controlling variable speed drives, sensors, or any device equipped with a current or voltage input. The module features 1500 V AC isolation between input and supply and 500 V AC between input and internal logic for robust noise immunity. The removable screw terminal block with 3.81 mm pitch simplifies wiring and maintenance. With IP20 protection and a compact 23.6 mm width, the TM3AI4 mounts easily on DIN rail conforming to IEC 60715 and integrates seamlessly via a simple interlocking assembly mechanism.
