Product Description
The Yokogawa SB401-11 S1 is an ESB Bus Interface Slave Module designed for use within the Field Control Unit (FCU) systems of the CENTUM VP distributed control system. It is mounted in ESB bus node units (e.g., ANB10S or ANB10D) and serves as the critical communication bridge between the FCU and various I/O modules via the ESB bus. The SB401-11 S1 supports high-speed and reliable communication and can be used in single or dual-redundant configurations depending on system design.
