Baseplate Assembly – Provides mechanical support and the interface to the I/O system.
Module Electronics – Handles signal conversion, isolation, and data processing.
Terminal Block – Enables secure connection of field wiring for analog signal inputs.
Each channel includes an independent A/D converter for consistent performance. The module’s LED indicators provide real-time diagnostics for power, module status, and communication.

Application Areas
The AI810 module is extensively used in:
Process Automation Systems (Oil & Gas, Chemical, Petrochemical)
Power Generation and Distribution
Water and Wastewater Treatment Plants
Pharmaceutical and Food Processing
Pulp and Paper Industries
Its high accuracy and robustness make it ideal for critical analog measurements like pressure, temperature, flow, and level signals.
Installation and Maintenance
Installation of the AI810 is straightforward — it mounts easily on a DIN rail and connects via a standard terminal base. Before installation, ensure that the module and backplane connectors are free of dust and debris.
Configuration: Set up input types and scaling using ABB Control Builder M.
Maintenance: Periodically check terminal connections and clean contacts to ensure signal integrity.
Replacement: Modules can be hot-swapped without shutting down the entire system, minimizing downtime.
Additional Information
Compliance: CE, UL, and RoHS certified.
Compatibility: Works seamlessly with ABB’s AC800M series CPUs and 800xA DCS platforms.
Lifecycle Support: ABB offers long-term service, spare parts, and firmware updates.
