Key Features and Benefits

Dual-Redundant Power Supply
The ANB10D-425/CU2N features dual-redundant power supplies for fault tolerance. Firstly, two power supply modules operate in parallel for continuous operation. In addition, if one supply fails, the other immediately takes full load without interruption. Specifically, the -4 suffix code explicitly indicates this dual-redundant configuration. Consequently, the ANB10D-425/CU2N maintains bus communication even during power supply maintenance. Therefore, critical processes continue running without disruption.

Flexible Power Input Options
The ANB10D-425/CU2N accommodates various site power configurations. Firstly, suffix code 2 specifies 220 to 240 V AC at 50/60 Hz for this model. In addition, other suffix options support 100 to 120 V AC or 24 V DC as alternatives. Specifically, the power consumption at 220 to 240 V AC is 230 VA and 120 W. Therefore, the ANB10D-425/CU2N adapts to global electrical standards.

Integrated ESB Bus Connector Unit
The ANB10D-425/CU2N includes the /CU2N option for ESB bus connectivity. Firstly, this connector unit provides reliable physical connections for the dual-redundant bus. In addition, it simplifies field wiring by consolidating bus connections in one location. Specifically, the connector unit is factory-installed and tested with the node unit. Consequently, the ANB10D-425/CU2N reduces installation time and eliminates field wiring errors.

High I/O Module Capacity
The ANB10D-425/CU2N supports up to 8 I/O modules in a single unit. Firstly, the weight of approximately 10 kg includes 8 I/O modules when fully populated. In addition, this high density reduces cabinet space requirements compared to distributed I/O solutions. Specifically, each I/O module connects to the ESB bus through the node unit. Therefore, the ANB10D-425/CU2N efficiently serves as a centralized I/O hub for control system applications.

Redundancy and Reliability Features

Dual-Redundant ESB Bus Support
The ANB10D-425/CU2N is designed for dual-redundant ESB bus architecture. Firstly, two independent bus paths connect the node unit to the field control station. In addition, the node unit automatically selects the active bus path for communication. Specifically, if one bus path fails, the other path continues operation seamlessly. Consequently, the ANB10D-425/CU2N provides fault-tolerant communication for critical processes.

Dual Power Supply Redundancy
The -4 suffix code on the ANB10D-425/CU2N provides power supply redundancy. Firstly, two power supply modules share the load under normal conditions. In addition, each power supply can handle the full load independently. Specifically, hot-swappable design allows replacement without powering down the node unit. Therefore, the ANB10D-425/CU2N achieves exceptional power availability for continuous processes.
