ANB10D-415/CU2N/NDEL

The Yokogawa ANB10D-415/CU2N/NDEL is a dual-redundant ESB Bus Node Unit for field input/output (FIO) configurations in Yokogawa distributed control systems. It provides the node-side interface between installed I/O modules and the Field Control Unit (FCU). This configuration specifies a dual-redundant power supply, a 100 to 120 V AC supply rating, a basic type without explosion protection, an ESB bus connector unit, and a node expansion software license.

Function and System Interface

The ANB10D functions as a local node connected to an FCU through the ESB bus. It communicates field analog and contact I/O signals to the controller and distributes power to the installed I/O modules. The node accommodates power supply modules, ESB bus interface slave modules, and field I/O modules within a rack-mounted assembly.

Power Supply and Redundancy

The -4 suffix specifies a dual-redundant power supply configuration, while 1 specifies the 100-120 V AC supply option. The documented hardware configuration uses two power supply modules and two SB401 ESB Bus Interface Slave Modules for dual-redundant operation. The selected power supply modules must match the ordered voltage configuration.

Connector Unit and Node Expansion License

The /CU2N option identifies the ESB bus connector unit configuration, comprising two S9562FA connector units. The /NDEL option is the node expansion software license; Yokogawa's model specifications identify this license as required when connecting the node unit to FCUs in the AFV10, AFV30, AFV40, and AFF50 families. Confirm the target FCU model and system configuration before ordering.

Frequently Asked Questions

Q: Does the ANB10D-415/CU2N/NDEL support dual-redundant operation?

A: Yes. The -4 suffix specifies the dual-redundant power supply configuration. The corresponding node hardware configuration uses two power supply modules and two SB401 bus interface slave modules.

Q: What does the /NDEL option provide?

A: It specifies the software license for node expansion. Yokogawa lists it as required for connecting the node unit with the specified AFV10, AFV30, AFV40, and AFF50 FCU families. Verify the applicable FCU and software configuration for the target system.

Q: Is this model suitable for applications requiring explosion protection?

A: No. The 5 suffix specifies the basic type without explosion protection. Applications requiring a specified explosion-protection classification need a separately confirmed model configuration.
