ABB AI895 3BSC690086R1 Analog Input IS HART 8 ch

Technical Specifications

Key Technical Characteristics

• HART Communication Integration: The AI895 supports HART pass-through, which allows maintenance software to communicate directly with smart field instruments. This capability facilitates remote calibration, asset management, and detailed device health monitoring through the S800 I/O bus.
• Intrinsically Safe Design: Built-in galvanic isolation and energy-limiting circuitry enable the module to interface directly with sensors in Zone 0, Zone 1, or Zone 2 hazardous areas. This eliminates the need for external zener barriers, significantly reducing installation complexity and hardware costs.
• Superior Measurement Accuracy: The module maintains an impressive accuracy rating of ±0.05%. Such high precision ensures that the DCS receives the most reliable data possible, which is fundamental for optimizing complex process loops and ensuring product consistency.

The ABB AI895 3BSC690086R1 is a high-performance, 8-channel analog input module specifically designed for the S800 I/O system. This module serves as an essential interface for Intrinsic Safety (IS) applications, allowing for the secure collection of data from field devices located in hazardous areas. By integrating HART (Highway Addressable Remote Transducer) protocol communication, the AI895 enables bi-directional data exchange, allowing operators to access advanced diagnostics and configuration data from smart transmitters without interrupting the analog signal.
