ANB10D-410/CU2T Yokogawa ESB Bus Node Unit

Hardware Specifications

Process Control Interface and Signal Connectivity

The Yokogawa ANB10D-410/CU2T manages FIO module communication through a dual-redundant ESB Bus interface. Moreover, the unit provides the local power distribution and physical mounting structure required for installed I/O modules. The CU2T option integrates ESB Bus termination components to maintain correct communication line impedance.

For Yokogawa process control applications, the node unit supports interface structures associated with 4-20 mA HART loop protocol, FOUNDATION Fieldbus / Profibus PA connectivity, channel-to-channel isolation, and cold junction compensation (CJC) functions through compatible FIO modules. Therefore, the ANB10D operates as the hardware platform for integrating field measurement and control signals into the CENTUM controller network.

The dual power supply architecture separates the power feed paths for improved system availability during individual supply module maintenance. In addition, the local backplane design supports module replacement procedures with the specified hot-swap restrictions of the installed FIO hardware configuration.

Frequently Asked Questions

Q: Does the ANB10D-410/CU2T support dual-redundant communication operation?
A: Yes. The unit provides a dual-redundant ESB Bus interface for communication between FIO modules and the connected Field Control Unit.

Q: How many FIO modules can be installed on this node unit?
A: The ANB10D-410/CU2T supports up to 8 FIO modules installed on the local node structure.

Q: What power supply configuration does this model use?
A: The model uses a dual-redundant power supply configuration with a 100 to 120 VAC input supply.

Field Installation Guidelines

Install the ANB10D-410/CU2T in the specified 19-inch rack structure and secure the chassis using the required mounting hardware. Verify that the rack provides sufficient airflow because the unit uses natural convection cooling.

Connect the ESB Bus cables according to Yokogawa installation requirements and install the CU2T termination components at the designated communication points. Maintain proper cable routing separation between signal wiring and power wiring to reduce electrical interference.

Before connecting the node unit to an FCU, confirm that the required ESB Bus Coupler Module, such as EC401 or EC402, is installed in the applicable Field Control Unit slots. Check power supply polarity, grounding conditions, and module seating status before system energization.
