Product Description
Product Overview
The Yokogawa SSB401-53 S1 is an ESB Bus Interface Slave Module designed for use in the ProSafe-RS Safety Instrumented System (SIS). This module connects safety node units (e.g., SNB10D) to the Extended Serial Bus (ESB), a high-speed, redundant communication network critical for safety applications. It facilitates reliable data exchange between safety control units and I/O modules, supporting SIL 3 safety standards. The SSB401-53 S1 is commonly deployed in industrial environments such as oil & gas, chemical processing, and power generation, where robust and fault-tolerant communication is essential.
