ABB CI627A 3BSE017457R1

Product Overview

ABB CI627A, part number 3BSE017457R1, is an AF100 Bus Administrator communication module built for ABB Advant OCS and AC800M / System 800xA distributed control systems. It acts as the master network management unit for the AF100 fieldbus, coordinating data transmission between controllers, I/O stations and field nodes across the control network.

This module schedules bus access, handles message routing and performs continuous bus health monitoring. It detects communication errors, short-circuit and line faults on AF100 bus, and reports alarms back to the DCS controller. With galvanic isolation, it protects control hardware from surge and electromagnetic noise in heavy industrial environments. It is an obsolete ABB component, widely used for spare replacement, overhaul and retrofit of legacy Advant and 800xA control cabinets in power, pulp & paper and petrochemical industries.
