Features:
- Interface Between Field Analog Instruments and AC 800M Controller Backplane
- Integrates Capability of 8-Channel Analog Signal Acquisition with HART Protocol Communication
- Functions in Conjunction with S800 I/O Modules and Standard ABB AC 800M Controllers
The ABB AI845-EA 3BSE023675R2 operates as the Analog Input S/R HART 8-channel module in a S800 I/O rack, providing reliable analog signal processing and HART device communication for all connected field instruments. It continuously converts incoming 4-20mA current signals or voltage signals from up to 8 channels and transmits this data through the rack backplane to support steady state operation of the control system. Seamless HART communication is standard with the AI845-EA 3BSE023675R2, enabling direct digital access to smart device parameters without requiring additional HART multiplexers.
The AI845-EA 3BSE023675R2 provides essential analog input functions common to the entire I/O station, and is a critical component of the measurement path, directly affecting the proper, normal operation of the overall control system. One or multiple AI845-EA 3BSE023675R2 modules can be installed per rack depending on the required channel count. The AI845-EA 3BSE023675R2 occupies a standard I/O slot in the rack and can be located in any available position within the S800 I/O configuration.
For expanded analog input applications, the S800 I/O system allows additional AI845-EA 3BSE023675R2 modules to be installed alongside other I/O modules. In addition to standard single module operation, the modular configuration also performs channel-level diagnostics. The S800 I/O system executes signal monitoring using the internal circuitry specified in the AI845-EA 3BSE023675R2 options.
The AI845-EA 3BSE023675R2 ABB Analog Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
