Product Description
The SB401-53 ESB Bus Interface Slave Module is a dedicated communication interface designed for Yokogawa distributed control systems. Developed for stable, high-speed ESB bus data exchange, this module enables direct connectivity between Field Control Stations (FCS) and ESB Bus Node Units within CENTUM VP architectures.
Engineered for continuous industrial operation, the SB401-53 integrates seamlessly into FIO node assemblies, delivering deterministic communication performance while maintaining a compact mechanical footprint. Its design supports both single and redundant ESB bus configurations, enhancing system availability in critical process environments.
Technical Overview
The SB401-53 functions as an ESB bus slave interface, handling I/O module data transmission between control processors and distributed I/O subsystems. It complies with Yokogawa ESB bus specifications and supports high-throughput cyclic communication required for real-time control applications.
The module is manufactured in Japan under Yokogawa quality standards and is supplied in brand-new condition with original factory packaging.
