Product Description
The YCB301-C020 is a precision-engineered 36-pin interconnect solution specifically designed for Yokogawa’s Extended Serial Backplane (ESB) control architecture. This high-integrity communication cable facilitates the vital link between a Field Control Station (FCS) and its associated I/O expansion units.
The YCB301-C020 (Model: YCB301-C020) is built to industrial standards, ensuring deterministic data transfer and minimal signal attenuation across the bus. Measuring 20 cm in length, this variant is optimized for short-range connections within a single cabinet or between adjacent racks, effectively reducing cable clutter and improving airflow.
The cable utilizes high-grade 24 AWG wiring and robust shielding to maintain 100Ω characteristic impedance, making it highly resistant to electromagnetic interference (EMI) commonly found in dense automation environments.

Application and Installation
The YCB301-C020 is primarily used to bridge the communication gap between the master ESB bus module (such as the ANB10 or AFV30) and expansion I/O nests. Its 36-pin configuration ensures that all control and diagnostic signals are synchronized.
The compact 20 cm length is specifically requested by engineers for “daisy-chaining” expansion racks where minimal latency and maximum cable neatness are required.
FAQ
Can I use the YCB301-C020 for external cabinet connections?
Due to its short 20 cm length, it is exclusively intended for internal cabinet connections. For inter-cabinet wiring, longer variants of the YCB301 series should be used.
Does this cable support redundant ESB configurations?
Yes, in a redundant ESB setup, two YCB301-C020 cables are typically required to establish independent paths for Bus 1 and Bus 2.
