ABB CI871K01 3BSE048847R1 AC 800M Communication Interface Kit

The ABB CI871K01 3BSE048847R1, also cataloged as the CI871K01 Communication Interface Kit, operates as a dedicated hardware component for high-speed deterministic Ethernet data exchange within ABB AC 800M controller setups. Installed directly on the controller CEX-Bus backplane, the interface module translates real-time control commands between System 800xA automation architectures and remote distributed I/O blocks, variable frequency drives, and field instrumentation.

Hardware Specifications

Backplane Bus Communication Velocity and Network Integration

The CI871K01 communication interface kit optimizes backplane bus communication velocity across the AC 800M CEX-Bus infrastructure. Utilizing an integrated baseplate interface, the module processes high-density I/O frame cycles at speeds up to 100 Mbit/s without degrading central processor performance. Internal firmware flash compatibility ensures continuous runtime signal monitoring and automated frame validation. In the event of network disruption, local hardware watchdog circuits drive connected output points into predefined fail-safe execution states to maintain process integrity.

Frequently Asked Questions

Q: What physical parts are included in the CI871K01 interface assembly kit?

A: The CI871K01 kit contains the CI871 processor module hardware along with its dedicated TP867 baseplate unit for direct CEX-Bus mounting.

Q: Can the CI871K01 module be replaced while the AC 800M controller is online?

A: Yes, the unit supports hot-swap maintenance procedures, allowing online replacement without de-energizing the main processor rack or interrupting adjacent modules.

Q: How is primary operating power delivered to the module electronics?

A: Power is supplied through the underlying CEX-Bus rail interface at a nominal +24 VDC, drawing approximately 160 mA under typical operating conditions.

Field Installation Guidelines

Isolate local field power lines and observe standard ESD protective precautions before handling the CI871K01 assembly. Mount the TP867 baseplate cleanly onto the DIN rail, then align the CI871 communication module vertically into the baseplate guides until both latch mechanisms lock into position.

Ensure all industrial communication cables and shield terminations remain physically separated from high-voltage motor drivers and switching lines. Ground the baseplate rail directly to the enclosure protective earth (PE) busbar using heavy gauge copper grounding braid to maintain full compliance with ISA 71.04 G3 harsh environment ratings.
