ABB CI868K01 3BSE048845R1

The ABB CI868K01 (3BSE048845R1) is an IEC 61850 communication interface module designed for the ABB AC 800M controller platform and System 800xA DCS environment. It provides a standardized communication bridge between process automation systems and electrical substation devices, enabling seamless integration with intelligent electronic devices (IEDs), protection relays, and power automation systems. 

The module is mainly used in applications where industrial control systems need to exchange real-time electrical data using the IEC 61850 communication standard, supporting modern substation automation and power management solutions. 

Product Parameters

Core Functions

1. IEC 61850 Network Integration

The CI868K01 enables AC 800M controllers to communicate with IEC 61850-compliant devices, including:

• Protection relays
• Bay controllers
• Intelligent electronic devices (IEDs)
• Substation automation equipment

It allows process control systems and electrical automation systems to operate within a unified communication architecture. 

2. MMS Communication

The module supports MMS (Manufacturing Message Specification) communication for:

• Real-time monitoring
• Status information exchange
• Measurement data acquisition
• Control commands between systems

3. GOOSE Communication

Through IEC 61850 GOOSE messaging, the CI868K01 supports fast peer-to-peer signal exchange for applications such as:

• Protection interlocking
• Trip signals
• Electrical equipment status exchange
• High-speed automation logic

ABB documentation specifies that one CI868 interface can support up to 120 IEDs for GOOSE communication and 40 IEDs for MMS communication (depending on configuration).
