ABB CI873K01 3BSE056899R1 S800 I/O EtherNet/IP Communication Interface Kit

The ABB CI873K01 3BSE056899R1, also cataloged as the CI873K01 Communication Interface Module, operates as a dedicated hardware component for fieldbus network integration within ABB S800 I/O setups. The assembly converts internal ModuleBus backplane protocols into deterministic EtherNet/IP and industrial network frames, executing cyclic data exchange and diagnostics between distributed I/O clusters and higher-level automation controllers.

Hardware Specifications

Backplane Bus Communication Velocity and Network Integration

The CI873K01 interface processes high-speed backplane bus communication velocity to pass input and output signals between local S800 expansion modules and the main control architecture. Operating with a typical current draw of 200 mA from the +5 VDC ModuleBus supply, the module executes deterministic I/O scans across up to 12 connected expansion cards. Built-in galvanic isolation protects internal processing micro-logic from ground potential shifts and industrial field noise. The module continuously validates firmware flash integrity and protocol frame timing, forcing attached output modules into predefined safe states whenever communication disruptions occur.

Frequently Asked Questions

Q: How many I/O modules can a single CI873K01 interface manage?

A: A single CI873K01 module manages communication for up to 12 S800 I/O modules within a connected local cluster over the ModuleBus backplane.

Q: How does the module indicate communication or hardware faults?

A: The front panel features dedicated diagnostic LEDs that display real-time operational status, including active power/run state, internal hardware faults, and network communication activity.

Q: What power source supplies the CI873K01 module during operation?

A: The module draws power directly from the internal +5 VDC ModuleBus backplane rail provided by the base termination unit.

Field Installation Guidelines

Power down the ModuleTermination Unit (MTU) and disconnect network lines before installing or removing the CI873K01 interface module. Align the module housing vertically with the MTU slot guides and press down evenly until the locking latches snap into position to secure backplane pin connections.

Route Ethernet and network interface cables through dedicated low-voltage wiring troughs away from high-power AC conductors to limit electromagnetic noise. Ground the DIN rail mounting assembly directly to the central equipment enclosure ground terminal, ensuring earth bonding resistance measures less than 1 Ohm for adequate industrial noise immunity.
