Product Description

The Yokogawa YCB301-C020 is a specialized short-reach ESB (Extended Serial Backplane) / ER bus communication cable designed for high-density interconnection between Field Control Units (FCUs) and ANB / ANT node units. Featuring 36-pin to 36-pin high-density connectors, this cable provides a deterministic, low-latency data path essential for real-time control synchronization.

With a compact 20 cm length, the YCB301-C020 is optimized for side-by-side module installations within a single control cabinet, reducing cable congestion, improving airflow, and maintaining excellent signal integrity in high-speed DCS architectures such as CENTUM VP and ProSafe-RS.

Technical Specifications

Application Scenarios

The YCB301-C020 is intended for compact DCS cabinet layouts where FCUs and I/O node units are mounted in immediate proximity. Typical applications include:

• High-density CENTUM VP control cabinets

• ProSafe-RS safety system enclosures

• Oil refineries and offshore platforms

• Pharmaceutical and specialty chemical plants

It is particularly effective where minimal cable length, reduced impedance, and clean cabinet organization are required.

FAQ

Q: When should I choose the 20 cm version over longer YCB301 cables?
The YCB301-C020 is best suited for adjacent or stacked modules. Shorter length minimizes impedance, avoids excess cable loops, and improves cabinet airflow compared to 1 m or 2 m variants.

Q: Is the YCB301-C020 compatible with both ESB and ER bus modules?
Yes. The YCB301 series is the standard physical interconnection for ESB and ER bus architectures, supporting modules such as EC401 and EC402.
