製品紹介
The Yokogawa YCB301 is a high-performance ESB Bus Cable specifically designed for use in Yokogawa’s CENTUM VP and CENTUM CS 3000 control systems. As a core component in the Enhanced System Bus (ESB) communication infrastructure, this shielded cable ensures high-speed, deterministic, and noise-immune data transfer between Field Control Stations (FCS) and various system modules or I/O components.
The YCB301 is engineered with multi-layer shielding, twisted-pair conductors, and high-durability insulation, making it suitable for both cabinet wiring and extended plant installations in harsh industrial environments. It supports dual-redundant ESB topologies, and its design meets Yokogawa’s stringent standards for reliability, safety, and long-term lifecycle support.
