Yokogawa Centum VP, Yokogawa DCS
Yokogawa Node Unit ANB11S, ANB11D
Node Unit for Single ESB Bus with Optical Repeater (for FV30S, FV30D, AFV40S, AFV40D)
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
