Product Description

The Yokogawa YCB301-C100 is a specialized high-speed communication cable designed for the ESB (Extended Serial Backplane) and ER bus architectures. This 36-pin to 36-pin shielded bus cable enables deterministic, real-time data exchange between Field Control Units (FCUs) and ANB / ANT node units in CENTUM VP and ProSafe-RS control systems.

Engineered for industrial control cabinets, the YCB301 series ensures low-latency communication, stable synchronization, and high signal integrity, which are essential for distributed I/O coordination in both process control and safety systems.

Technical Specifications

Application Scenarios

The YCB301-C100 is commonly used when expanding Yokogawa DCS architectures, particularly when adding additional I/O nodes to an existing control station. Typical installation environments include:

• Central control rooms

• Local equipment rooms and shelters

• Petrochemical and refinery facilities

• LNG processing plants

• Large-scale power generation systems

It is a standard interconnection component for distributed ESB / ER bus-based I/O architectures.

FAQ

Q: Can the YCB301-C100 be used for ER Bus communication?
Yes. The YCB301 series supports both ESB and ER bus interfaces, provided installation distances remain within allowable limits for the 1-meter cable length.

Q: Does this cable support redundant configurations?
Yes. In redundant FCU systems, two YCB301-C100 cables are typically installed—one for Bus 1 and one for Bus 2—to maintain high-availability communication paths.
