Yokogawa Optical Repeater Dual-Redundant ESB Bus Node Unit ANB11D-425/BU2A
Node Unit for Dual-Redundant ESB Bus with Optical Repeater (for AFV30/AFV40)
The ESB Bus Node Unit has an interface function that
communicates the analog I/O signals and contact I/O
signals of a field with a Field Control Unit (FCU) via an
ESB bus, as well as a function that supplies power to the I/O Modules.
This node units are connected to FCU via an ESB bus.
