Product Details
The CI857K01 3BSE018144R1 is professional INSUM Communication Module for ABB AC800M DCS platform, it acts as key AC800M Motor Control Interface Unit for connecting controller with INSUM‑based intelligent motor control centers.
This module adopts ABB proprietary INSUM bus protocol, it can access up to 128 intelligent motor protection and control devices. It transmits motor running current, voltage, working state, fault code and other real‑time data to AC800M main CPU through CEX‑Bus backplane bus, and receives control commands to realize remote start‑stop and parameter modification of motors. It supports hot‑swap function, module can be replaced without shutting down the control rack, reducing system maintenance downtime.
Front‑panel LED indicators show module power status, CEX‑Bus communication and INSUM bus link condition. Built‑in hardware self‑diagnosis monitors bus communication quality and internal hardware status, fault information will be uploaded to DCS operation station. Industrial‑grade circuit design meets strict EMC requirements for power plant and heavy‑industry cabinet environment.
Standard rack‑slot mechanical structure. Widely applied in thermal power, petrochemical, pulp‑paper and metallurgy industries with large‑scale motor control centers. It is essential communication hardware for MCC system reconstruction, intelligent motor point expansion and defective INSUM interface module replacement for legacy AC800xA automation projects.
