Yokogawa Optical Repeater Dual-Redundant ESB Bus Node Unit ANB11D-220/BU2B
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.
Hardware Specifications

Node Connection
When connecting an ESB Bus Node Unit to FCU, install ESB Bus Couple Module (EC401 or EC402) to FCU (*1).
EC401 or EC402 must be installed in slot 7 and slot 8. To make single configuration, EC401 or EC402 must be installed in slot 7, and slot 8 must be empty.
*1: AFV30 , AFV40 , AFV10 , or AFF55 .
