ABB CI868AK01 3BSE092691R1 AC 800M Communication Interface Package

Configured for IEC 61850 Edition 2 substation protocol integration in System 800xA network architectures, the ABB CI868AK01, also cataloged as the CI868A IEC 61850 Communication Interface Package, provides direct physical and electrical execution of Manufacturing Message Specification (MMS) client and Generic Object-Oriented Substation Event (GOOSE) data frames. The assembly interfaces directly with the CEX-Bus backplane on ABB AC 800M controllers, combining power grid substation monitoring and industrial process control into a single execution environment.

Hardware Specifications

CEX-Bus Deterministic Network Integration & Protocol Execution

The CI868A module utilizes onboard logic to manage real-time communication task schedules over the CEX-Bus backplane, maintaining deterministic data handshakes without overburdening the primary AC 800M processor CPU. Dedicated internal DC/DC converter circuitry converts incoming +24 VDC system power into isolated board-level operating voltages. Network communication relies on high-speed Ethernet drivers supporting 10/100 Mbit/s transmission speeds with channel isolation to shield internal logic against common-mode electrical noise. Hardware code locks integrated into the TP867 baseplate physically prevent incorrect module insertion during field maintenance. Furthermore, the unit supports hot-swap replacement under live backplane power, eliminating system shutdowns while maintaining protocol link state consistency across the System 800xA control network.

Frequently Asked Questions

Q: Can the CI868AK01 module be hot-swapped while the AC 800M controller remains powered?

A: Yes, the CI868A communication module supports online hot-swapping on the TP867 baseplate. Furthermore, field technicians must ensure that substituting the module does not disrupt critical GOOSE network subscriber paths before unlatching the hardware from the CEX-Bus.

Q: How does the TP867 baseplate prevent accidental insertion of wrong module types?

A: The TP867 baseplate incorporates a mechanical code lock system. Furthermore, technicians must align the physical keying mechanisms on both baseplate and module prior to insertion, ensuring that incompatible I/O or communication hardware cannot make electrical contact with the CEX-Bus power and signal rails.

Q: Is network redundancy supported directly on the single CI868A Ethernet port?

A: No, the CI868A hardware interface does not support dual-port network redundancy on a single module. Furthermore, fault-tolerant network topology requires installing duplicate CI868A modules across separate CEX-Bus positions within the same AC 800M controller framework.

Field Installation Guidelines

• Baseplate Mechanical Mounting: Latch the TP867 baseplate securely onto the standard 35 mm DIN rail prior to sliding the assembly onto the CEX-Bus backplane connector. Ensure all mechanical locking tabs click into position to maintain grounding continuity across the backplane structure.
• Shield Grounding and Cable Routing: Fasten STP (Shielded Twisted Pair) Cat 5e or Cat 6 Ethernet cables using standard RJ45 connectors. Connect all cable shields to the main cabinet functional ground bus bar using low-impedance grounding clamps to mitigate high-frequency electromagnetic interference.
• Drain Wire and Ground Bus Termination: Route the backplane ground connection directly to the main protective earth (PE) bus. Maintain cable bends above minimum bend radius limits (typically 4x outer cable diameter) and segregate network Ethernet lines from high-voltage AC motor wires by at least 200 mm within cabinet wire ducts.
