ABB AI880A

ABB AI880A is a high integrity analog input module designed for single and redundant configurations.

The following is a detailed introduction about ABB AI880A:

Functions and features:

AI880A has 8 current input channels, each channel can be voltage or current input.

Its input resistance is 250 ohms and is capable of handling short circuit conditions in the transmitter supply without damage.

This module distributes external transmitter power to each channel, simplifying connections and making power distribution to 2-wire or 3-wire transmitters more convenient.

Transmitter power is monitored and current limited.

The AI880A supports configurable over-range and under-range limits and has a 0.1% temperature drift maximum.

It has built-in current limiting transmitter power to protect the device from damage due to excessive current.

The module complies with NAMUR recommendation NE43 and has a 50 ppm/°C input filter (rise time 0-90% of 190 ms).

Its update cycle time is 10 milliseconds, ensuring the real-time and accuracy of data.

Technical specifications:

The power supply of the AI880A module is generated by the 24V voltage on the ModuleBus.

Maximum field cable length is 600 meters (656 yards) and maximum input voltage (lossless) is 11 VDC.

The module has a high-precision analog input function that can accurately measure and transmit analog signals to ensure the stability and accuracy of industrial processes.

At the same time, its wide measurement range enables it to adapt to different industrial environments and application needs.

AI880A adopts anti-interference measures such as shielding and filtering to effectively suppress interference signals and ensure signal stability and accuracy.

Its high-quality electronic components and materials ensure high reliability and stability, meeting the needs of long-term operation in industrial environments.

Application areas:

AI880A modules are widely used in industrial automation systems, such as winding, drawing, metering, and guide wires in the chemical fiber industry; flat glass annealing furnaces, glass kiln mixing, edge stretching machines, and bottle making machines in the glass industry; electric arc furnaces Automatic feeding, batching systems and intelligent control of elevators, etc.

In addition, it can also improve process level and product quality, and is also widely used in CNC machine tool control, automobile production lines, papermaking, elevators and other fields.

In short, ABB AI880A is a powerful and stable analog input module suitable for various industrial automation application scenarios.
