Features:
- Redundant PROFIBUS DP-V1 communication with hot-swap support
- Electrical and optical ModuleBus connection for distributed S800 I/O
- TU846 or TU847 mounting with documented redundancy handling
ABB identifies CI840A 3BSE041882R1 as redundant profibus dp-v1 fieldbus communication interface for ABB S800 I/O. The interface supports redundant operation, hot swap, HART pass-through and electrical or optical ModuleBus connection. ABB specifies a 24 VDC supply, TU846/TU847 mounting and a capacity of up to seven optical clusters. The complete ordering identity is important because related units can differ in channel arrangement, termination design, interface function or supported system generation. Selection should therefore be based on the article number, nameplate and installed configuration rather than appearance alone.
Technical content is limited to ABB CI840A product data and S800 I/O documentation. Final suitability is confirmed against the installed unit, nameplate and system records.
The ABB CI840A 3BSE041882R1 redundant PROFIBUS DP-V1 fieldbus communication interface is supported by Moore Automated for verified industrial replacement and spare-part requirements.

Station Interface Role
CI840A establishes the documented PROFIBUS DP-V1 connection between AC 800M and S800 I/O while supporting the required ModuleBus arrangement.
Redundancy Configuration
Confirm the TU846/TU847 base, redundant partner, electrical modules and optical cluster count before replacement.
Commissioning Checks
Preserve node address and controller configuration, inspect the bus and ModuleBus connections, and follow ABB startup diagnostics.
