Key Specification
Core Features & Advantages
-
Flexible Signal Compatibility: The module's standout feature is its support for multiple analog signal types—voltage (0...10 V and bipolar ±10 V) and current (0...20 mA and 4...20 mA) . It also provides extended current ranges and scalable data mapping (-32768 to 32767) for greater application flexibility.
-
High Precision and Fast Processing: With 12-bit/11-bit+sign resolution, Sigma-delta conversion, and ±0.2% full-scale accuracy, the module delivers reliable signal acquisition . Each channel is sampled in approximately 1 ms, enabling responsive real-time control.
-
Compact and Robust Design: Housed in a 23.6 mm-wide IP20-rated enclosure weighing just 0.11 kg, the module saves cabinet space . It features 1500 Vac isolation between input and supply and 500 Vac isolation between input and internal logic, with twisted-pair shielded cable support up to 30 m for noise immunity. Designed for DIN rail or panel mounting, it meets EN/IEC 61131-2 standards and carries CE, cULus, RCM, and EAC certifications.
Typical Applications
The TM3AI8 is widely used in industrial automation for precise analog signal measurement and integration, such as:
-
Process Monitoring: Measuring temperature, pressure, flow, and level in manufacturing and process control systems .
-
Machine Control: Receiving feedback from sensors, transducers, and variable speed drives in packaging, material handling, and robotics applications .
-
Data Acquisition: Capturing analog signals from field devices for real-time processing and system diagnostics
FAQ
Q1: Which PLC platforms are compatible with the TM3AI8?
A: The TM3AI8 is fully compatible with Modicon M221, M241, M251, and M262 logic controllers via the TM3 expansion interface. It cannot be used with older M200 or M100 controllers, which use the TM2 module architecture with a different physical and electrical interface.
Q2: What types of analog signals can the module read?
A: The TM3AI8 supports voltage (0...10 V and -10...+10 V) and current (0...20 mA and 4...20 mA) signals, including extended measurement ranges. Each of the 8 channels is independently configurable for either voltage or current input.
Q3: Can I mix different signal types on the same module?
A: Yes. Each of the eight channels is individually configurable via EcoStruxure Machine Expert or SoMachine. For example, you can assign channels 1-4 to 4-20mA current input and channels 5-8 to ±10V voltage input within the same module instance.
Q4: Are the channels isolated from each other?
A: No, the inputs share a common ground, so isolation between channels is not provided. However, the module does include common-mode isolation between inputs, supply, and internal logic for improved signal integrity.
Q5: How is the module configured?
A: Configuration is performed through EcoStruxure Machine Expert (formerly SoMachine) using the Modicon controller's programming environment. No additional software license is required; support is included in the base installation.
