Yokogawa ANB10D-425/CU2N CENTUM VP ESB Bus Node Unit

The Yokogawa ANB10D-425/CU2N is an ESB Bus Node Unit designed for field control applications within CENTUM VP distributed control systems. It operates as an interface between field analog and contact I/O signals and a Field Control Unit (FCU) via an ESB bus connection, while supplying power to up to 8 installed I/O modules. Built with dual-redundant power supplies and dual ESB bus interfaces, the ANB10D-425/CU2N ensures continuous communication, field transmitter power distribution, and signal processing for critical industrial process control environments.

Features

• Interfaces field analog and contact I/O signals directly with a Field Control Unit via an ESB bus connection.
• Houses up to 8 field I/O modules and provides internal power distribution to modules and connected field transmitters.
• Includes dual-redundant power supply module slots and dual SB401 ESB Bus Interface Slave Module slots.
• Standard 19-inch rack-mount hardware layout using four M5 screw attachment locations.
• Configured with a 220–240 V AC power input and standard non-explosion protection design.
• Ships with the /CU2N dual-connector unit option for connecting dual-redundant ESB bus lines.

Applications

• DCS process automation in refining, petrochemical, and chemical facilities
• Thermal and nuclear power generation control systems
• Industrial water, wastewater, and utility monitoring platforms
• Continuous manufacturing process control and Field Control Unit node expansion

Installation Guidelines

• 19-Inch Rack Mounting: Mount the unit on a standard 19-inch rack using four M5 screws and four S9049PM insulating bushes included as accessories.
• Power Terminal Wiring: Secure field power wiring to the dual power supply terminals using M4 terminal screws.
• Barrier Insulation Partition: If installing I/O modules with built-in intrinsic safety barriers, install an insulating partition (Part No. T9083NA) at the 8th slot.
• Bus Coupler Placement: Ensure the host Field Control Unit uses EC401 or EC402 ESB Bus Coupler Modules installed in slots 7 and 8 to interface with the node unit.
