Overview

The ABB AI820 Analog Input Module is a highly versatile device designed for precise signal acquisition in AC 800M automation systems. This module features four differential and bipolar input channels, each capable of being configured for either voltage or current input. Engineered for demanding industrial environments, the AI820 ensures reliable performance and protection against accidental voltage applications.

Functional Highlights

The AI820 module supports a wide array of input signals, including ±20 mA, 0-20 mA, 4-20 mA, -10 to +10 V, 0 to 10 V, 2 to 10 V, -5 to +5 V, 0 to 5 V, and 1 to 5 V DC bipolar differential inputs. This flexibility makes it compatible with various sensors, enhancing its usability across different applications.

Moreover, this module includes robust protection features. Each channel can withstand overvoltage of up to 30 V DC, and built-in current sense resistors help safeguard the channel reliability. The AI820 also distributes external transmitter supply to each channel, simplifying the integration of two-wire transmitters without additional current limitations.

All channels are electrically isolated from the ModuleBus as a single group, maintaining signal integrity in electrically noisy environments. The module operates on a 24 V supply derived from the ModuleBus, ensuring efficient power management.

With 14-bit resolution including a sign, the AI820 provides high-precision measurements essential for process monitoring and control. Additionally, it supports HART communication, allowing for advanced diagnostics and configuration, greatly enhancing system performance and longevity.
