Description
ABB CI522A is a Redundant AF100 Fieldbus Interface Module
Model: CI522A | Part No: 3BSE018283R1
Product Title & Description
The ABB CI522A is a Redundant AF100 Fieldbus Interface Module, belonging to ABB Advant OCS / AC400 controller family. It connects Advant Master controllers to S800 remote I/O stations via AF100 fieldbus, supporting dual redundant AF100 bus links for high availability. Widely deployed in thermal power, pulp & paper, metallurgy and chemical plants. It is a key spare for legacy ABB Advant DCS cabinet maintenance and retrofit.
Core Product Overview
CI522A is rack-mounted communication card with two independent AF100 bus ports for redundant bus topology.
- AF100 bus speed: 1 Mbps
- Dual AF100 ports (A / B), hot redundancy support; automatic switchover if one bus path fails
- It handles data exchange between AC400 / AC160 Advant controllers and S800 I/O units (DI/DO, AI/AO, pulse modules)
- Front panel LED indicators for module status, port link, bus communication and fault alarm
- Onboard self-diagnostics for bus short, cable break, module hardware fault
Lifecycle note: CI522A is discontinued. Only available as NOS or refurbished spare for existing Advant OCS systems.

FAQ
Q1: What is used for? A1: Redundant interface module, connecting Advant AC400 controllers to S800 remote I/O stations over fieldbus.
Q2: Does support communication redundancy? A2: Yes, dual ports (A/B). When one bus cable fails, system automatically switches to the backup path without control interruption.
Q3: Is still in production? A3: Discontinued. Only NOS and refurbished spare available for legacy Advant system maintenance.
Q4: What devices connect to ? A4: S800 series distributed I/O units via twisted pair bus.
Q5: Warranty for original ABB 3BSE018283R1? A5: Original / refurbished unit carries standard 12-month factory warranty under proper installation and operating conditions.
Installation & Configuration Guide
7.1 Pre-installation Preparation
Verify board, inspect backplane connector and dual front ports. Prepare shielded twisted pair cables, Advant rack, I/O stations and bus terminators. Power off rack before installation, wear ESD protection.
7.2 Installation Steps
Insert into empty Advant rack slot and lock the module. Wire A/B bus cables to front connectors, install terminators at each bus segment end. Single-point shield grounding inside control cabinet. Check rack backplane power and protective earthing.
7.3 System Configuration & Commissioning
Power up rack, check module LED status. Configure bus address and I/O station list in Advant engineering tool. Test redundancy: disconnect bus A to verify automatic switchover to bus B and no control loss. Simulate cable break to check fault alarm. Save system configuration database.
7.4 Maintenance & Precautions
During plant outage, inspect connectors, cable shielding and PCB dust accumulation. Keep cabinet clean. If communication dropout occurs, check bus terminator, cable integrity and grounding before replacing .
