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

Description

The YOKOGAWA ANB10D-420/CU2N is a dual-redundant ESB Bus Node Unit designed for use in YOKOGAWA DCS systems. Key features include dual-redundant ESB bus and dual-redundant power supply, which work together to maximize system reliability and operational stability. The dual-redundant ESB bus minimizes the risk of system interruptions caused by bus failures, while the dual-redundant power supply ensures continuous operation if one power source malfunctions. This unit operates on a 220-240V AC power supply, with the suffix code “-4” indicating its dual-redundant power configuration. It features a compact design with a depth of only 65mm, saving installation space. For communication, it supports Ethernet (Modbus/TCP) protocol, and can also achieve Modbus/RTU, P2P (peer-to-peer), Coordinated operation, and PC-Link communication via RS-485. Additionally, it can connect to open networks such as PROFIBUS-DP and CC-Link, enabling seamless data exchange with other devices or systems. The included /CU2N is an ESB bus connector unit; optional accessories include /CU2T (ESB bus connector unit with terminator), /NDEL (node expansion software license, required for connection with AFV10, AFV30, AFV40, and AFF50), and /ATDOC (explosion-proof manual).
