Schneider TM3AI4G

The Schneider Modicon TM3 Series Analogue Input Module, part number TM3AI4G, is a compact and versatile solution designed for seamless integration into various industrial control systems. This module is engineered to work in conjunction with the Modicon M221, M241, M251, and M262 controllers, offering a broad range of compatibility for diverse applications.

Equipped with four analogue inputs, the TM3AI4G module can handle a variety of signal types, including current ranges from 4 to 20 mA and 0 to 20 mA, as well as voltage ranges from 0 to 10 V and -10 to 10 V. This flexibility makes it suitable for gathering and processing signals from a wide array of sensors and transducers in automation setups.

The module boasts a high-resolution 12-bit analogue-to-digital converter, ensuring precise and accurate readings. The input resolution is further enhanced with 11 bits plus sign for differential measurements, providing users with detailed and reliable data for monitoring and control tasks.

Designed for durability and reliability, the TM3AI4G can withstand continuous overloads up to 13 V for voltage inputs and 40 mA for current inputs. Its input impedance is optimised for both current and voltage signals, with <= 50 Ohm for current and >= 1 MOhm for voltage, minimising the impact of external electrical noise and ensuring stable performance.

The module's conversion time is swift, with a 1 ms response per channel plus an additional millisecond for the controller cycle time, allowing for real-time data processing and control actions. The sampling duration is equally efficient at <= 1 ms, facilitating quick signal acquisition.

For ease of installation, the TM3AI4G module is designed to mount on standard DIN rails, including both top hat type TH35-15 and TH35-7.5 rails, conforming to IEC 60715. It also offers the option for plate or panel mounting with a fixing kit, providing flexibility for various enclosure configurations.

The module's dimensions are compact, with a height of 90 mm, a depth of 70 mm, and a width of 23.6 mm, making it an ideal choice for space-constrained environments. Its green LED indicator for power status ensures clear visibility of the module's operational state.

In summary, the Schneider Modicon TM3 Series Analogue Input Module TM3AI4G is a high-performance, adaptable component that delivers accurate and rapid signal processing capabilities, making it an essential part of any modern industrial automation system.
