ANB11D-215-BU2A fiber optic dual redundant ESB bus node unit
ANB11D-215-BU2A is a fiber optic ESB bus node unit of Yokogawa CENTUM VP FIO architecture, serving as a communication hub between FCU field control units and FIO series I/O modules.
ANB11D-215-BU2A uses fiber optic media to achieve ESB bus communication, with stronger resistance to electromagnetic interference; The backplane provides communication links and power supply for the I/O modules, and can connect up to 8 FIO analog/digital I/O modules to complete data exchange between on-site process signals and DCS controllers.
BU2A is equipped with dual fiber optic ESB bus interfaces for the middle position of the fiber optic ESB bus link; The whole machine is powered by a single power supply of 200-240VAC; ANB11D-215-BU2A has built-in hardware self diagnosis, which monitors the status of power supply, bus, and slot I/O modules in real time. Fault information is uploaded to the DCS system to ensure stable and continuous operation of chemical and refining equipment.

ANB11D-215-BU2A fiber optic dual redundant ESB bus node unit
Product features
- Fiber optic dual redundant ESB bus (BU2A): Using fiber optic transmission of ESB bus signals, compared to copper cables, it is resistant to strong electromagnetic interference and suitable for high interference conditions; Dual fiber optic bus redundancy, automatic switching in case of single fiber optic link failure, without interrupting I/O communication; Used as an intermediate node in the fiber optic ESB bus link.
- Single power supply: 215 is equipped with a 200-240VAC single channel AC power input.
- 8-slot I/O expansion: The backplane slot supports up to 8 FIO series analog and digital I/O modules, enabling centralized access of on-site signals.
- Complete hardware self diagnosis: Real time detection of power supply, fiber optic bus, and slot module status, reporting fault information to the DCS system for quick location of fault points.
- Standard 19 inch rack installation: Cabinet rack installation, compatible with industrial control cabinets, convenient for project integration and maintenance.
- The I/O module supports hot swapping: replacing the FIO module does not require the entire machine to be powered off, reducing device downtime losses.
- Excellent EMC anti-interference: Fiber optic transmission avoids strong electromagnetic interference on site and is suitable for complex industrial environments such as power plants and chemicals.
- System compatibility: Compatible with CENTUM VP system and used with AFV30/AFV40 field control units.
