Analog input module, 8 current/voltage inputs, high resolution, screw terminals TM3AI8

Analog Input Module for Automation Systems

This analog input module, designed to work with Modicon TM3 systems, expands the capabilities of PLCs to measure analog signals. It allows connecting up to 8 current or voltage sensors or signal sources, making it a versatile solution in industrial and building automation applications. High 12-bit resolution ensures precise readings, and screw connections guarantee reliable and durable electrical connections.

Features and Application

The TM3AI8 module is ideal for systems requiring monitoring and control based on analog values. It finds application in areas such as:

• HVAC Systems: reading temperature, pressure, humidity.
• Industrial Automation: measuring currents, voltages, signals from level or flow sensors.
• Process Monitoring: collecting data from sensors to optimize production processes.
• Building Systems: controlling lighting, ventilation, and heating based on sensor data.

Thanks to the ability to accept both current and voltage signals, the module eliminates the need for additional signal converters in many applications. This translates into saving space and installation costs.

Specification and Benefits

The TM3AI8 module is characterized by compact dimensions (23.6 mm wide, 90 mm high, and 70 mm deep), making it easy to mount in control cabinets with limited space. Power consumption at 1.1W minimizes the impact on the energy consumption of the entire system. Screw terminals provide a solid connection of wires, eliminating the risk of loosening connections during operation – especially important in industrial environments exposed to vibrations.

It is worth noting the 12-bit resolution for analog inputs – this guarantees accurate measurements even with small changes in the input signal. No need for additional protection (no explosion-proof protection category) simplifies installation in standard industrial and building applications. The module does not have safety functions (PL/SIL), so remember to use appropriate protection at the control system level if required by the application.
