ANB10D-410/CU2N Yokogawa ESB Bus Node Unit

Hardware Specifications

Process Control Signal Interface and Isolation Characteristics

The Yokogawa ANB10D-410/CU2N operates as an FIO node interface within the CENTUM architecture. Moreover, the unit transfers field I/O data through the ESB communication path while maintaining separated power and communication functions.

The node supports Yokogawa process control configurations that include analog and digital signal modules. In addition, compatible I/O modules can process standard instrumentation interfaces such as 4-20 mA HART loop protocol, FOUNDATION Fieldbus, and Profibus PA connectivity when installed according to the selected module configuration.

The hardware structure supports channel-to-channel isolation requirements through the installed I/O modules. Therefore, field signal wiring and control network communication remain separated according to the module-level electrical design.

Frequently Asked Questions

Q: Does the ANB10D-410/CU2N support redundant ESB communication operation?
A: Yes. The unit provides a dual-redundant ESB bus configuration through the CU2N connector option, allowing connection to redundant ESB communication paths.

Q: How many I/O modules can be installed on the ANB10D-410/CU2N chassis?
A: The node unit accommodates up to 8 I/O modules together with required power and bus interface components.

Q: Which power supply configuration does this model require?
A: The ANB10D-410/CU2N uses a dual-redundant power supply configuration with 100 – 120 VAC input and typically operates with PW481 power supply modules.

Field Installation Guidelines

Install the ANB10D-410/CU2N in a compatible Yokogawa cabinet or 19 inch rack structure using the specified mechanical mounting points. Verify rack grounding before connecting ESB bus cables and field wiring.

Route ESB communication cables separately from high-voltage power cables to reduce electromagnetic interference. Furthermore, connect cable shields according to Yokogawa grounding practices and maintain proper separation between signal and power wiring.

Confirm the installed power supply modules match the required voltage range before energizing the node unit. Check connector seating, module locking mechanisms, and redundant bus connections during commissioning.
