SCHNEIDER TM3AI4 Used Working Modicon TM3 Analog Input

Product Overview

The Schneider Electric TM3AI4 is a high-density Analog Input Module belonging to the Modicon TM3 expansion system. Designed for use with Modicon M221, M241, and M251 logic controllers, this module provides four high-resolution analog inputs in a slim, space-saving form factor. It is exceptionally versatile, allowing each channel to be individually configured for voltage (0-10V, -10...+10V) or current (4-20mA, 0-20mA). This Used Working unit is perfect for process monitoring applications such as reading pressure sensors, flow meters, or level transmitters with industrial-grade precision.

Key Features

• 4-Channel High Resolution: Provides four independent analog inputs with 12-bit (or 11-bit + sign) resolution for accurate data acquisition.
• Flexible Input Types: Supports multiple signal ranges, including 0...10 V, -10...+10 V, 0...20 mA, and 4...20 mA, configurable via software.
• Seamless Bus Integration: Features the "top-hat" bus connector for high-speed data exchange with the M221/M241/M251 CPU without the need for external data cabling.
• Hot-Swappable Terminals: Equipped with a removable screw terminal block, allowing for quick module replacement without disconnecting individual field wires.
• Fast Sampling Rate: Offers a conversion time of 1ms per channel, ensuring rapid updates for dynamic process variables.
• Slimline Design: At only 23.5mm wide, it allows for high-density I/O configurations in compact electrical enclosures.
• Robust Diagnostic LEDs: Includes a front-panel status LED to indicate module health and bus communication status at a glance.

Item Condition (Used - Working)

• Functional Status: Used - Working. This module has been salvaged from a functional automation panel. All four channels have been tested for signal accuracy and stable communication with a Modicon M221 controller.
• Physical State: Very good condition. The terminal block is intact, and the bus connector pins are straight and clean. Minor scuffs on the plastic housing are present but do not affect performance.
• Technical Integrity: The module has been cleared of any previous diagnostic errors and is ready to be addressed in your next EcoStruxure project.
• Visual Reference: Please examine the high-resolution images to verify the specific hardware revision; the unit pictured is the exact TM3AI4 module you will receive.
