Yokogawa SSB401-53 ESB Bus Interface Slave Module

  • Yokogawa’s SSB401-53 is an ESB Bus Interface Slave Module engineered exclusively for safety instrumented systems (SIS)—the backbone of hazard mitigation in high-risk industrial environments like refineries, chemical plants, and power generation facilities. As a core component of Yokogawa’s ProSafe-RS SIS, this module does far more than just pass signals along; it acts as the critical bridge that links safety node units (SNB10D) to the system’s SB Bus.
  • This SB Bus isn’t just any communication network—it’s a high-speed, redundant infrastructure that’s non-negotiable for the ProSafe-RS SIS to function reliably. Redundancy here means the bus can keep operating seamlessly even if one communication path fails, a must-have feature for SIS where downtime or signal loss could lead to catastrophic consequences. The SSB401-53’s role in this setup ensures that safety-related data flows consistently between node units and the central system, keeping the entire SIS synchronized and ready to respond to process anomalies at a moment’s notice.
