Functional Description
The ABB AI820 module withstands accidental 30 V DC connections, protecting against voltage misapplication. Engineers benefit from integrated 250W current sense resistors rated at 5 Watts, safeguarding one channel at a time. The module distributes external transmitter supply to each channel, simplifying wiring for two-wire transmitters.
Signal Handling
The ABB AI820 supports multiple input ranges including -20…+20 mA, 0…20 mA, 4…20 mA, -10…+10 V, and 1…5 V DC. Its 14-bit resolution plus sign ensures accurate measurements across diverse industrial applications. Input shunt resistors remain protected up to 30 V DC, enhancing reliability.
Design and Build
The ABB AI820 measures 18.5x8.5x30.5cm and weighs 1.08kg, making it suitable for compact installations. Power derives from the 24 V ModuleBus supply, while all four channels remain isolated as a single group to reduce interference.
Applications and Compatibility
The ABB AI820 Analog Input Module integrates seamlessly with Advant-800xA and AC 800M systems. Engineers deploy it in process industries, chemical plants, and manufacturing lines requiring precise signal acquisition. Its HART communication capability supports smart transmitters, enabling advanced diagnostics and configuration.
