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.

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).
