ABB CI855K01 Dual Ethernet Port Interface Module – AC 800M Controller Series
When a critical Ethernet communication link fails on the plant floor, the consequences cascade instantly — SCADA systems lose visibility, distributed I/O nodes go silent, and operators are left managing a process blind. In high-stakes environments such as power generation, oil & gas, and chemical processing, even seconds of communication loss can trigger emergency shutdowns or costly production interruptions. The ABB CI855K01 (3BSE018106R1) Dual Ethernet Port Interface Module is engineered precisely to eliminate this single point of failure, providing redundant, high-availability Ethernet connectivity for ABB AC 800M controllers.
Within the AC 800M product family — ABB’s flagship process automation controller platform deployed across thousands of industrial sites worldwide — the CI855K01 occupies a critical communication tier. It delivers dual, independently operable Ethernet ports that support both redundant network topologies and simultaneous multi-network connectivity, making it the preferred interface module for engineers designing fault-tolerant control architectures. Its 3BSE018106R1 catalog reference confirms factory-original ABB specification, ensuring full compatibility with PM8xx processor modules and the System 800xA engineering environment.
