Product Description

The SB401-10 S1 is a high-speed communication slave module for the Yokogawa CENTUM VP Distributed Control System (DCS). It serves as the primary interface for an I/O node, enabling real-time data exchange between remote I/O units and a Field Control Station (FCS) via the Extended Serial Backplane (ESB) bus.

Designed for high-availability industrial environments, the S1 revision ensures long-term stability and deterministic performance. Its modular form factor allows seamless integration into node interface units, providing a robust backbone for distributed process control across large plant installations.

Technical Specifications

Application Scenarios

• Distributed I/O Expansion
  Connecting remote I/O racks to a central FCS for field device management.

• High-Density Process Control
  Linking multiple analog and digital modules in power generation or petrochemical plants.

• System Redundancy Upgrades
  Dual-module deployment ensures zero data loss during single-bus failures.

Product FAQ

Q: What does the "Slave" designation mean?
A: The slave module resides in the I/O node and receives instructions from the master interface card in the FCS, ensuring coordinated data flow across local and remote racks.

Q: Is this module compatible with the ER Bus?
A: No. The SB401-10 S1 is specifically designed for the ESB Bus. Systems using the ER Bus require a different interface module (e.g., EB series).
