Product Description
The ANB11D-615/BU2A is a high-performance optical interface node designed for the Yokogawa CENTUM VP distributed control system. It enables long-distance communication between remote I/O modules and the Field Control Unit (FCU) by converting electrical ESB bus signals into optical signals.
The “6” series designation indicates suitability for harsh industrial environments, featuring ISA G3 conformal coating and an extended operating temperature range (-20°C to 70°C).
This unit is equipped with dual-redundant 100–120 V AC power supplies, ensuring high system availability through parallel redundancy across all eight I/O module slots. The integrated BU2A connector supports both star and chain fiber optic topologies, enabling flexible and resilient network design.

Its extended temperature range allows stable operation even in cabinets exposed to fluctuating HVAC conditions or harsh outdoor environments.
Technical FAQ
Q: What is the difference between the ANB11D-5 series and the 6 series?
A: The 6 series includes ISA G3 protection and an extended temperature range (-20°C to 70°C), while the 5 series is intended for standard industrial environments without enhanced corrosion protection.
Q: Does this unit include fiber optic transceivers?
A: No. The ANB11D-615/BU2A provides the interface node, but optical repeater modules (e.g., ANT401, ANT411) must be installed separately to complete the fiber optic communication link.
