CI856K01 3BSE026055R1 S100 I/O Interface | ABB AC 800M Spare Parts
The ABB CI856K01 3BSE026055R1 is an S100 I/O communication interface module designed for ABB AC 800M distributed control systems. It connects the AC 800M controller to ABB S100 I/O racks through a TP856 baseplate, enabling reliable data exchange between the controller and field I/O signals.
This module is commonly used in migration, retrofit, and spare-parts projects where existing S100 I/O installations need to be integrated with AC 800M / System 800xA controllers. One CI856K01 can connect up to five S100 I/O racks, with each rack supporting up to 20 I/O boards.
- S100 I/O interface for AC 800M — Connects AC 800M controllers to ABB S100 I/O systems.
- Supports up to 5 S100 I/O racks — Each rack can hold up to 20 I/O boards.
- TP856 baseplate included — Houses a 36-pin mini-ribbon connector for S100 I/O rack connection.
- CEX bus connection — Connects to the AC 800M CEX bus and is powered through the processor unit.
- Hot-swappable — Supports module replacement during operation in applicable configurations.
- Legacy I/O reuse — Helps retain existing S100 I/O wiring and terminal installations during system upgrades.
- DIN-rail mounting — Easy installation in industrial control cabinets.
- AC 800M communication with ABB S100 I/O racks
- Migration from legacy ABB Advant Master / OCS systems to AC 800M
- Reuse of existing S100 I/O wiring and terminal blocks
- Process control systems in power, chemical, oil & gas, and manufacturing plants
- System maintenance, replacement, and spare parts stocking
- Retrofit projects requiring continued use of S100 I/O hardware

The CI856K01 3BSE026055R1 is specifically an S100 I/O interface for AC 800M — not a general-purpose fieldbus module such as PROFIBUS DP, Modbus TCP, EtherNet/IP, or PROFINET. Before procurement, please confirm the S100 I/O rack model, baseplate type (TP856), CEX bus configuration, firmware compatibility, and whether redundant controller support is required in your application.
The HS code may vary by destination country and customs interpretation. Please confirm the final HS code with your customs broker before shipment.
