ABB CI851K01 is an AC 800M PROFIBUS DP interface package containing the CI851 communication module and TP851 baseplate. The interface operates as a DP Master Class I and supports standard PROFIBUS DP communication rates from 9.6 kbit/s to 12 Mbit/s. One bus segment supports up to 32 nodes, with galvanic isolation and a female DB9 connector on the TP851. ABB documents status indicators for error, run and traffic, IP20 protection and no hot-swap support. CI851 is not approved for use in an AC 800M High Integrity controller. Exact hardware, wiring, bus termination and controller compatibility must be reviewed before installation.
Condition, availability and warranty are Stockoems commercial information, not manufacturer commitments.
CI851 connects to the controller communication expansion bus.
The module manages a PROFIBUS DP segment.
The baseplate provides the documented field connection.

CI851K01 provides a PROFIBUS DP Master Class I connection for supported AC 800M controllers. The CI851 module handles bus communication while the TP851 baseplate provides the DB9 field connector. Reliable operation depends on compatible controller hardware, correct CEX-bus placement, approved PROFIBUS cable and termination, node addressing, segment loading and project configuration.
Match CI851K01 and order code 3BSE018101R1 exactly. Verify the CI851 module, TP851 baseplate, controller type, CEX-bus slot, firmware, engineering software, DB9 wiring, cable, segment termination, node addresses and bus speed. ABB states that CI851 cannot be used in an AC 800M High Integrity controller and does not support hot swapping.
