Product Overview
The ABB CI865 is the dedicated communication interface that links the AC 800M controller platform to the Satt ControlNet bus. It bridges different bus standards, allowing older Satt I/O systems (Rack I/O and Series 200 I/O) to operate seamlessly with the AC 800M. This module is not a general-purpose ControlNet interface and is not suitable for High Integrity controllers.
Key Features and Benefits
- Connects Satt 19-inch rack I/O and Series 200 I/O to AC 800M.
- Supports online replacement (Hot Swap) – no configuration required before installation.
- Handles I/O scanning of up to 31 distributed I/O systems.

Industry Applications
The ABB CI865 is ideal for facilities that have legacy Satt I/O installations and want to migrate to the AC 800M controller without replacing existing field wiring. It enables a cost-effective upgrade path while preserving investments in Satt 19-inch rack I/O and Series 200 I/O.
Typical applications include:
- Process control upgrades in chemical and pharmaceutical plants.
- Retrofit projects in power generation and water treatment.
- Expansion of distributed I/O networks in manufacturing lines.
Installation & Setup
Since the ABB CI865 supports Hot Swap, you can replace it online without system downtime. No configuration is required before installation, simplifying the swap procedure. Mount the module onto the CEX bus and connect the Satt ControlNet cable to the BNC connector. Ensure the bus is terminated correctly and that the module is seated firmly.
Maintenance & Reliability
The CI865 is built for continuous operation in industrial environments. Its IP20 protection and G3 corrosion resistance make it suitable for typical control cabinets. Periodic inspection of the BNC connection and bus cabling is recommended to maintain signal integrity. With no moving parts and passive cooling, the module offers long service life with minimal upkeep.
Compatibility & Integration
The ABB CI865 works exclusively with AC 800M controllers and Satt ControlNet networks. It supports up to 31 distributed I/O nodes and up to 4 units per CEX bus. It does not operate as a general ControlNet interface and is not certified for High Integrity controllers. Verify system compatibility before ordering.
Selection Guide & Purchasing Advice
Before purchasing the ABB CI865, confirm your controller model and the Satt I/O system version. Ensure that your CEX bus has available slots and that the BNC cabling is in good condition.
