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.

Product Applications

The YCB301 cable is purpose-built for interconnecting control modules, I/O subsystems, and FCS units within Yokogawa’s process automation architecture. Its low signal attenuation and excellent electromagnetic shielding make it ideal for:

• ESB Bus Communication Backbone – Ensures stable and synchronous data transfer between FCS and field I/O.

• Redundant Bus Structures – Enables dual-redundant cabling for safety and fault-tolerant communication.

• Industrial Control Cabinets – Clean and reliable internal wiring for panel-to-panel data links.

• Remote I/O Segments – Supports long-distance transmission for distributed control installations.

• High-Noise Environments – Robust signal integrity even near heavy-duty machinery or high-frequency equipment.

Its performance and certifications make the YCB301 suitable for use in oil & gas, chemical processing, water treatment, power plants, and pharmaceutical manufacturing.
