Description
Product Overview
The ABB AI895 is a high-performance 8-channel analog input module designed for industrial automation systems, specifically engineered for applications requiring precise signal conditioning and HART communication capabilities. Belonging to ABB’s S800 I/O series, this module serves as a critical component in distributed control systems (DCS) and process automation platforms, enabling seamless integration with controllers such as the AC 800M. Its core function is to convert analog signals from field devices (e.g., pressure transmitters, temperature sensors) into digital data for real-time monitoring and control .
Key to the ABB AI895’s value is its dual-mode signal handling—supporting both 4–20 mA current loops and voltage inputs while maintaining HART protocol compatibility. This allows it to interface with 2-wire transmitters in hazardous areas, providing power to the device while simultaneously acquiring measurement data. The module’s intrinsic safety certification (ATEX/IECEx) ensures safe operation in explosive environments, making it ideal for oil & gas, chemical, and pharmaceutical industries .
With 12-bit resolution and ±0.1% accuracy, the ABB AI895 delivers reliable measurements even in high-noise environments. Its configurable input filter (0–140 ms rise time) and diagnostic capabilities (over/undervoltage detection, open-circuit monitoring) minimize false alarms and reduce downtime. The module’s compact form factor (45 mm width) and DIN rail mounting further enhance its suitability for space-constrained installations .
