The Yokogawa S9346FA is an ESB bus connector unit with integrated terminator, designed for Yokogawa CENTUM VP / CENTUM CS 3000 Distributed Control Systems (DCS).
It combines both bus connection and termination functions in a single module, simplifying system architecture while ensuring stable communication across the ESB (Extended Serial Backplane) network. This unit is typically used at the end of an ESB bus segment, where proper termination is required to prevent signal reflection and maintain data integrity.
According to Yokogawa system documentation, S9346FA is specifically defined as a connector unit with terminator for ESB bus systems, often used together with optical ESB repeater modules.
