📘 Product Overview
Model: ANB10D‑415
Product Type: ESB Bus Node Unit (for field I/O)
Brand: Yokogawa
Series / Family: ESB / Node Interface Units
The ANB10D‑415 is a node unit used in Yokogawa’s ESB (Enhanced Safety/Fieldbus) network architecture. It links field I/O modules (FIO or I/O cards) to the ESB bus and acts as a communication and power interface. In many installations, a version ANB10D‑415/CU2N is used, indicating dual ESB connectors (for redundancy). This node unit is designed for reliable, deterministic communication in industrial control systems.
It supports dual-redundant bus connectivity, supplies power to connected modules, and includes diagnostics and fault tolerance features suited for continuous operation in harsh industrial environments.
📐 Technical Specifications
