The ABB AI810 (3BSE008516R1) is a high-performance 8-channel analog input module engineered for the S800 I/O distributed control system. This module provides versatile signal processing, supporting both current (0–20 mA, 4–20 mA) and voltage (0–10 V DC, 2–10 V DC) inputs, with each channel independently configurable to meet specific field device requirements.
Features
8 single-ended, unipolar analog input channels.
12-bit resolution for precise signal conversion.
Integrated PTC resistors protect inputs against overvoltage and short-circuit conditions up to 30 V DC.
Supports transparent HART communication for digital data transmission alongside analog values.
Electrically isolated channel group (8 channels isolated from ground) to reduce electromagnetic interference.
Compatible with a wide range of S800 Module Termination Units (MTUs).
Applications
The AI810 is widely utilized in critical industrial environments, including:
Refinery Process Control: Monitoring level, flow, and pressure transmitters in storage and distillation units.
Turbine Auxiliary Systems: Managing critical data such as lube oil pressure and cooling water temperature.
Boiler Control: Providing real-time feedback on fuel feed rates and water levels.
Renewable Energy: Supporting hydraulic pressure and pitch control management in large-scale power generation.

Installation Guidelines
Ensure the system power is completely disconnected before inserting or removing the module from the MTU.
The module must be mounted on a compatible S800 MTU (e.g., TU810, TU812, TU830).
Use shielded twisted-pair cabling for analog signals to minimize noise; ensure shields are properly grounded at the designated common point.
Maintain proper ventilation in the control cabinet to prevent heat buildup, as the module dissipates 1.5 W.
Handle with standard ESD precautions to prevent damage to sensitive internal circuitry.
FAQ
Is the AI810 compatible with HART?
Yes, the AI810 is designed to allow transparent transmission of HART communication signals, enabling digital data to pass through alongside the analog process values.
Which MTUs can be used with this module?
The AI810 is compatible with various S800 series MTUs, including the TU810, TU812, TU814, TU818, TU830, TU833, TU835, TU838, and TU850.
What protection is provided for the inputs?
