Overview

The ABB CI855K01 Interface Module plays a vital role in the transition from older Advant OCS systems to ABB’s System 800xA architecture. It establishes a reliable communication link between AC 800M controllers and legacy Advant Controllers (e.g., 410, 450) using the MasterBus 300 protocol.

This module supports dual Ethernet ports for redundancy, ensuring continuous communication even during network failures. Its hot-swap capability allows for maintenance without system shutdown, which reduces downtime and improves overall operational efficiency.

Additionally, the CI855K01 is equipped with robust electrical isolation and reverse polarity protection, safeguarding against potential surges and wiring errors. This makes it particularly well-suited for mission-critical applications in industries such as power generation, oil and gas, and process control.

Technical Data

Typical Applications

• Legacy System Integration: Connects Advant Controllers to AC 800M without requiring a full system replacement.

• Substation Automation: Facilitates communication between legacy protection devices and modern control systems.

• Process Control Modernization: Enables phased upgrades in chemical, oil & gas, and manufacturing plants.

• Power Generation Facilities: Ensures communication continuity in turbine and generator control systems.

• Industrial Redundancy Architectures: Supports fault-tolerant designs with dual Ethernet connectivity.

Example: In a refinery control room, the CI855K01 allows legacy Advant controllers to communicate with newer AC 800M units, enabling the continued use of existing assets while allowing for future scalability. This makes it an ideal solution for hybrid system environments.
