Product Description

Overview

The ABB CI522A (3BSE018283R1) is an advanced AF100 Communication Interface Module designed for the Advant OCS and ABB 800xA systems. It bridges the S800 I/O system with the Advant Fieldbus 100 network, ensuring deterministic, high-speed communication for distributed automation networks. This module provides robust connectivity for controllers and remote I/O stations, supporting high system availability in critical process control environments.

Description

The CI522A installs on terminal bases such as TU541 or TU548 and functions as a communication plug-in for the S800 I/O cluster. It supports redundant media paths, enabling uninterrupted data exchange even in the event of link failures. The module features integrated diagnostics, including front-panel LEDs for Run, Fault, and Warning status, as well as hot-swap capability, allowing maintenance without halting operations.

The AF100 protocol delivers precise timing and deterministic updates, making it ideal for closed-loop control processes. Up to 12 S800 I/O modules can be connected per cluster, with flexible network distances supported via twisted pair, coaxial cable, or fiber optics with external modems.

Performance & Key Characteristics

• High-Speed Data Transfer: AF100 protocol ensures deterministic communication with up to 1.5 Mbit/s throughput.

• Media Redundancy: Provides continuous operation under fault conditions.

• Hot-Swap Capable: Supports “Hot Configuration in Run” (HCIR) for module replacement without process interruption.

• Scalable Integration: Connects up to 12 S800 I/O modules per cluster.

• Self-Diagnostics: Continuous monitoring of communication and module status; LEDs indicate Run, Fault, and Warning states.

• Environmental Protection: Conformal G3 coating and wide operating temperature range allow reliable operation in harsh industrial environments.

Technical Specifications (Summary)

Applications

• Communication link for S800 I/O clusters to AC410, AC450, or AC800M controllers.

• Mission-critical process control where redundancy and deterministic timing are required.

• Integration with ABB Ability™ System 800xA for advanced process monitoring and control.

FAQ
