The Yokogawa ABC11D Dual-Redundant Bus Converter is an advanced communication interface module designed to enhance the reliability and integrity of data transmission within Yokogawa’s Distributed Control Systems (DCS). This module serves as a critical link that manages and converts bus signals between redundant communication paths, ensuring uninterrupted data flow even in the event of a failure in one of the communication channels.

The dual-redundant design allows the ABC11D to simultaneously monitor two separate bus lines, automatically switching between them without data loss or interruption. This feature is essential in high-availability industrial environments where system downtime can lead to costly production losses or safety hazards.
