Product Description
The Yokogawa SB401-11 is an ESB Bus Interface Slave Module designed for use in ESB bus node units such as ANB10S and ANB10D. It serves as the communication gateway between field I/O signals and a Field Control Unit (FCU) within Yokogawa’s CENTUM VP control system. The SB401-11 ensures stable data transmission across the ESB bus and plays a crucial role in both single and dual-redundant system architectures.
