SEC401-11 S3 Bus Coupler Module Yokogawa RX3i AC Voltage Input Module A: It uses conformal coatingProduct Description The Yokogawa SEC401 11 is a high performance S3 (Synchronous Serial Single) Bus Coupler Module designed for the CENTUM VP Distributed Control System (DCS). It functions as the hardware interface for extending S3 bus communication between a Field Control Station (FCS) and associated I O expansion units. By enabling deterministic, real time synchronization across distributed I O nests, the SEC401 11 ensures minimal latency and stable
