ABB CI867K01 3BSE043660R1 Modbus‑TCP Communication Interface Module
CI867K01 (3BSE043660R1) is a Modbus‑TCP communication interface module for ABB AC 800M Control System. It serves as a dedicated network gateway, realizing bidirectional data exchange between the AC800M controller and Modbus‑TCP field devices such as remote I/O units, variable frequency drives, power meters and third‑party instruments over standard industrial Ethernet.
This compact S800 I/O compatible module adopts galvanic isolation design for Ethernet ports to resist industrial site electromagnetic interference. It supports hot‑swap online replacement without stopping the whole control rack, and works together with CI867 terminal unit TU810V1. Conformal coated PCB ensures stable operation under harsh factory and power‑plant environmental conditions.
