Product Procurement & Buyer Guide

Understanding the ANB10D-425 Model Code

The model code ANB10D-425 defines a specific configuration for industrial use. The "ANB10D" base indicates a Node Unit for a dual-redundant ESB bus. The suffix "-4" specifies a dual-redundant power supply module. The "2" suffix denotes a 220-240 V AC power supply requirement. The "5" suffix confirms this is a basic type unit. This unit lacks any explosion-proof certifications for hazardous areas. You must verify your plant's power supply voltage before ordering. This model provides high availability through its redundant power architecture.

Power Supply and Consumption Details

This unit accepts specific AC and DC voltage inputs for operation. The ANB10D-425 runs on 100-120 V AC or 220-240 V AC. It also accepts 24 V DC as an alternative power source. The power consumption varies with the input voltage you select. At 100-120 V AC, it consumes 200 VA and 120 W. At 220-240 V AC, it consumes 230 VA and 120 W. The DC input draws a steady 5.5 A for operation. You must choose the correct suffix code for your plant’s voltage. This flexibility allows global deployment without major hardware changes.

Mechanical Mounting and Physical Specifications

The unit uses a standard 19-inch rack mounting system for installation. You secure it with four M5 screws into the rack rails. The package includes an insulation bush as a standard accessory. The total weight is approximately 10 kg with eight I/O modules. This weight includes the node unit and the connector hardware. Plan your rack layout to support this weight distribution. Ensure adequate ventilation around the unit for heat dissipation. This design simplifies integration into existing Yokogawa control systems.

Option Codes for Bus Connection

The suffix codes define the connector unit for the ESB bus. The ANB10D-425 typically pairs with a specific connector option. The /CU2N option provides a standard connector unit for the bus. The /CU2T option includes a terminator for the bus end. You must select the correct option for your network topology. A terminator prevents signal reflections on the bus line. This choice is critical for maintaining communication integrity. Consult your system architecture diagram before selecting the option.

Ensuring System Redundancy and Reliability

The dual-redundant power supply is a key feature of this model. This design eliminates a single point of failure for power. If one supply fails, the second unit takes over seamlessly. This ensures continuous operation of your control network. The unit supports hot-swappable power supplies for easy maintenance. You can replace a faulty supply without shutting down the system. This feature maximizes your plant's operational availability. It is ideal for critical processes that cannot tolerate downtime.
