Description

The ABB AI820 3BSE008544R1 is an analog input module designed for use within the ABB S800 I/O system, primarily deployed in Advant OCS and System 800xA distributed control environments. This module provides high-precision data acquisition for industrial process control applications, converting analog field signals into digital values for the control system.

The unit features 4 differential and bipolar input channels, supporting a variety of current and voltage ranges. Each channel is equipped with individual channel-to-ModuleBus isolation and internal transmitter power supply distribution for two-wire transmitters. The AI820 also supports HART pass-through communication, allowing configuration and diagnostics of HART-enabled field instruments directly through the control system.

Features

4 differential, bipolar analog input channels
Supports current (0 to 20 mA, 4 to 20 mA) and voltage (up to ±10 V) ranges
14-bit plus sign conversion resolution
Built-in isolated transmitter power supply for 2-wire transmitters
HART communication pass-through support
ModuleBus communication for integration with S800 I/O clusters
Overvoltage protection on inputs up to 30 V DC

Applications

Process monitoring and control in chemical and petrochemical plants
Power generation turbine and auxiliary control systems
Water and wastewater treatment monitoring
Oil and gas upstream and downstream processing

Installation Guidelines

Verify that the control system power and ModuleBus power are de-energized before handling the module.
Inspect the module and base unit for any physical damage or bent pins.
Mount the module onto the designated S800 MTU (ModuleTermination Unit) baseplate.
Secure the module using the mechanical locking mechanism on the front housing.
Connect field cabling to the corresponding terminals on the MTU according to your system wiring diagrams.
Restore power and verify module status via the System 800xA engineering workplace or diagnostic LEDs.
