Product Overview
The ABB CI869 is a communication interface module designed for the AC 800M controller family. It connects the controller to the Advant Fieldbus 100 (AF 100) network via a twisted pair (TWP) medium, enabling seamless data exchange with other AC 800M, AC 160 controllers, and connectivity servers. The CI869 expansion unit integrates CEX-Bus logic, a communication unit, and an isolated DC/DC converter that derives its power from the +24 V supply through the CEX-Bus.
With support for both redundant cables and redundant communication interfaces, the CI869 ensures high availability in critical industrial processes. It also operates in AC 800M High Integrity systems, making it suitable for safety-related applications.

Real-World Applications
The ABB CI869 excels in industries where reliable communication and redundancy are paramount. For example, in a power generation plant, the CI869 connects the AC 800M controller to the AF 100 network, enabling real-time monitoring of turbine parameters. Its redundant configuration ensures that a single cable failure does not interrupt critical data flow.
In oil and gas facilities, the CI869 supports High Integrity systems, providing a safe communication path for emergency shutdown systems. The hot-swap feature allows maintenance teams to replace the module without halting production, significantly reducing operational losses.
For water treatment plants, the CI869 acts as a slave station on the AF 100 bus, receiving control commands from a master controller. Its robust environmental specifications (operating up to +55 °C) make it suitable for harsh industrial environments.
Installation & Setup Guidance
When installing the ABB CI869, ensure the AC 800M controller is powered off to avoid electrical hazards. Mount the module onto the CEX-Bus backplane, aligning the connectors carefully. Use the twisted pair cable to connect to the AF 100 network, and verify that the cable length does not exceed the recommended limit for 1.5 Mbit/s transmission.
For redundant configurations, install two CI869 modules and configure them in the controller software. Always follow the wiring diagram provided in the product manual to ensure correct polarity and termination.
Maintenance & Reliability
Regular inspection of the CI869 is essential for long-term reliability. Check the module's LEDs for proper status indication. Keep the enclosure clean and free from dust, as the IP20 protection rating does not guard against water ingress. Operate the module within the specified temperature range to prevent thermal stress.
Given its corrosion protection (G3 compliant to ISA 71.04), the CI869 is well-suited for environments with moderate levels of airborne contaminants. Periodically verify that the twisted pair connections are secure and free from corrosion.
Compatibility & Integration
The ABB CI869 is designed exclusively for the AC 800M controller family. It communicates with other AC 800M controllers, AC 160 controllers, and connectivity servers via the AF 100 protocol. The module also works with the CI527A hardware interface when used with the AC 100 OPC Server. For Advant Fieldbus 100 redundancy, two CI869 modules can be deployed.
Buying Guide
