YOKOGAWA | ANB10D-420/CU2N/NDEL | ESB Bus Node Unit

Description

The YOKOGAWA ANB10D-420/CU2N/NDEL is an ESB Bus Node Unit designed for high-reliability industrial automation systems. Equipped with dual redundant ESB buses, it significantly boosts communication reliability by reducing the risk of system interruptions caused by bus failures. It also supports dual redundant power supplies, which enhances module operational stability—if one power supply malfunctions, the other can immediately take over to maintain continuous operation.

This unit operates on 220-240V AC power and features a compact design with a depth of just 65mm, saving valuable rack space. It supports multiple communication protocols, including Ethernet (Modbus/TCP), and enables additional communication modes via RS-485, such as Modbus/RTU, P2P, Coordinated, and PC-Link. It also integrates with open networks like PROFIBUS-DP and CC-Link, facilitating seamless data exchange with other devices and systems.

Structurally, it has a total of 12 slots: 2 for power modules, at least 2 for communication modules (such as SB401), and up to 8 for I/O modules, allowing flexible configuration based on application needs. Primarily used in YOKOGAWA DCS systems to enable local node communication with field control units or other nodes, it is ideal for industries like chemical processing, power generation, and metallurgy where high reliability in automated control is critical.
