Product Overview
The S9341FA is a connector unit with integrated terminator designed for the Yokogawa CENTUM series DCS, specifically for the Extended Serial Backplane (ESB) Bus. It provides the physical connection for ESB bus cables and incorporates a built-in bus terminator, ensuring signal integrity by preventing reflections at the end of the communication line. This enables reliable, high-speed data transmission between Field Control Units (FCU) and associated I/O expansion units.
