Product Description
The ANB11D-215/BU2B is a high-availability optical interface node designed for Yokogawa’s CENTUM VP control architecture. It acts as a bridge between remote I/O modules and the Field Control Unit (FCU), using fiber optic communication to overcome the distance limitations of copper-based ESB bus connections.
The “2” series is optimized for 5 km optical repeater modules (e.g., ANT401), enabling reliable data transmission in geographically distributed industrial environments.
Equipped with a dual-redundant 100–120 V AC power supply, this unit ensures continuous I/O processing even in the event of a power failure. The BU2B connector interface supports optical bus topologies and provides full galvanic isolation, protecting control systems from lightning surges and electromagnetic interference.
