ABB CI868 3BSE048845R1 Communication Interface

Configured for IEC 61850 protocol data exchange in ABB System 800xA topologies, the ABB 3BSE048845R1 (CI868 IEC 61850 Communication Interface) provides direct physical/electrical execution across CEX-Bus backplane architecture. The module connects an AC 800M controller to substation automation devices via 10/100 Mbit/s Ethernet, processing MMS and GOOSE messaging structures to integrate electrical plant equipment into process control applications.

Hardware Specifications

ABB Backplane Bus & Deterministic Networks

The module relies on backplane bus communication velocity licenses to route high-speed GOOSE events and MMS traffic directly onto the CEX-Bus backplane. Running on deterministic Ethernet structures, the unit processes real-time electrical telemetry without degrading controller loop timing. Internal memory maintains firmware flash compatibility, allowing deterministic synchronization between the communication interface and High Integrity (HI) AC 800M control processors.

Frequently Asked Questions

Q: Does the CI868 interface support hot-swap replacement during system operation? A: Yes. The CI868 module mounts to the TP867 baseplate, which maintains CEX-Bus continuity. You can remove and insert the module while the AC 800M controller is powered without interrupting power or signal transmission across adjacent CEX-Bus modules.

Q: How does the module receive operating power, and does it require an external 24 VDC supply cable? A: Power is drawn directly from the controller backplane. The TP867 baseplate routes 24 VDC power and logic signals from the CEX-Bus directly into the module connector, drawing a typical operating current of 160 mA.

Q: Can the CI868 module be deployed in High Integrity (HI) safety controller configurations? A: Yes. The CI868 module operates alongside High Integrity AC 800M controllers, enabling non-interfering IEC 61850 substation data collection within safety-instrumented system environments.

Field Installation Guidelines

Observe the following field installation parameters during cabinet assembly and module replacement:

1. Baseplate Latching and CEX-Bus Setup: Attach the TP867 baseplate onto the DIN rail adjacent to the AC 800M processor or existing CEX-Bus module. Slide the baseplate horizontally along the rail until the CEX-Bus connectors mesh completely. Insert the CI868 module perpendicularly onto the baseplate until top and bottom locking tabs engage.
2. Ethernet Cable Routing: Plug shielded RJ45 CAT5e or CAT6 Ethernet cables into the front ports. Route all network cables through dedicated control cabinet wireways, keeping them isolated from 230 VAC or 480 VAC power lines to prevent electromagnetic coupling.
3. Shield Shielding and Enclosure Grounding: Connect the RJ45 cable drain wire and screen directly to the main cabinet ground bar via low-impedance ground clamps. Ensure the DIN rail bonding strap connects directly to local earth ground, and maintain a minimum of 5 full thread engagements on panel ground studs to satisfy industrial EMC standards.
