Product Description
The Schneider Electric TM3AI8 is an 8-channel analog input expansion module that forms part of the Modicon TM3 I/O system. Specifically designed for compatibility with Modicon M221, M241, and M251 logic controllers, this module allows the acquisition of analog signals from field devices such as pressure transmitters, temperature sensors, flow meters, and other industrial instrumentation.
With support for current (0–20 mA, 4–20 mA) and voltage (0–10 V) input signals, the TM3AI8 ensures precise and stable readings for process-critical data. It features a compact form factor and DIN rail mounting, making it easy to integrate into control panels and distributed automation systems.
Ideal for both OEM applications and complex industrial automation installations, this module offers a reliable and scalable way to expand analog signal handling capabilities within Schneider’s modular controller platforms.

Applications
The TM3AI8 module plays a vital role in a wide range of analog signal acquisition applications, where accurate data capture is essential for monitoring and control. These include:
Process Control Systems: Collects data from transmitters measuring flow, temperature, pressure, or chemical concentrations in industrial processes.
Building Automation: Reads signals from ambient sensors (humidity, CO₂, temperature) to optimize HVAC control.
Water and Wastewater Treatment: Interfaces with level, pH, and flow sensors for regulatory compliance and operational efficiency.
Energy Management: Captures data from power meters or sensors to support energy optimization strategies.
Food & Beverage Industry: Monitors analog sensors used in filling, pasteurization, and temperature-controlled storage.
Packaging Machines: Acquires analog input from load cells, positioning feedback, or torque sensors.
Advantages
High Channel Density: With 8 input channels in a single module, it maximizes signal acquisition per footprint.
Multi-Signal Support: Accepts both voltage and current signals, ensuring compatibility with diverse sensors.
Quick Signal Response: Conversion time of just 3 milliseconds per channel enables real-time applications.
Accurate and Stable: 12-bit resolution and ±0.5% full-scale accuracy offer precise signal processing.
Status Diagnostics: Built-in LED indicators provide channel-wise visual status for faster troubleshooting.
Compact Modular Design: Space-saving DIN-rail format aligns seamlessly with Modicon TM3 system architecture.
Seamless Integration: Fully recognized by EcoStruxure Machine Expert or SoMachine for configuration and programming.
No External Power Required: Powered directly from the base controller, reducing wiring complexity.
Frequently Asked Questions (FAQ)
Q: What PLC platforms support the TM3AI8 module?
A: It is fully compatible with Modicon M221, M241, and M251 PLCs via the TM3 expansion interface.
Q: What types of analog signals can this module read?
A: It supports 0–10 V voltage signals and 0–20 mA / 4–20 mA current signals.
Q: Can each input channel be configured independently?
A: Yes, each of the 8 channels can be independently configured for either voltage or current input.
Q: Are the channels isolated from each other?
A: No, the inputs share a common ground, so isolation between channels is not provided.
Q: How is this module configured?
A: It is configured through EcoStruxure Machine Expert (formerly SoMachine) using the Modicon controller’s programming environment.
Q: Can I use this module for thermocouples or RTDs?
A: No, the TM3AI8 is not suitable for direct connection to thermocouples or RTDs. Use dedicated temperature modules like TM3TI4.
Q: What cable length is recommended for analog sensors?
A: Cable lengths of up to 30 meters are typical, using shielded twisted-pair to reduce signal noise.
Q: Is there calibration required before use?
A: No, the TM3AI8 comes factory-calibrated and ready for deployment.
Q: What happens if an analog input wire breaks or shorts?
A: Input value will read as out-of-range, and diagnostics can be observed via LED indicators or controller software.
Q: Can this module be hot-swapped?
A: No. It is not hot-swappable. Power must be turned off before installation or removal.
