The ABB CI840A (3BSE041882R1) is a PROFIBUS DP-V1 Fieldbus Communication Interface (FCI) for the S800 I/O system, supporting redundant configurations (TU846/TU847 modules).
- Isolated power supply to I/O modules
- OSP handling and configuration
- Input power fused
- Hot Configuration In Run
The CI840A module strictly follows industrial grade standards in hardware design and can withstand harsh on-site environments. It has passed the G3 corrosion protection certification (ISA-S71.04) and can be used for a long time in air environments with moderate corrosiveness, such as chemical plants or offshore platforms.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description.
High performance communication: Supports PROFIBUS DP-V1 protocol to achieve seamless data exchange between controllers and field devices.
Redundancy Support: Designed specifically for high availability, supports 1+1 redundancy configuration. If redundant communication is required, two CI840A modules and one TU846 or TU847 terminal unit need to be ordered.
Hot swapping and online configuration: Supports hot swapping (Hot Swap) and hot configuration in operation (HCIR), allowing for module replacement or configuration changes without interrupting system operation.
HART transparent transmission: equipped with HART pass through function, convenient for remote calibration and diagnosis of on-site intelligent instruments.
Isolation power supply: Provides isolation power supply for I/O modules and has input power supply fuse protection function.
