Product Overview

The YCB301-C100 is a factory pre-terminated fully shielded ESB bus interconnection cable exclusively built for Yokogawa CENTUM VP and legacy CS3000 distributed control systems. The suffix C100 represents a fixed 1-meter standard length, dedicated to establishing high-speed internal communication links between Field Control Units (FCUs), ANB node adapters, dual redundant control racks and backplane expansion slots inside DCS central cabinets. It adopts closed foil shielding with a dedicated drain wire to block electromagnetic interference generated by frequency converters, high-power contactors and power distribution loops, eliminating data packet loss, communication timeout and controller offline faults caused by industrial electrical noise.

Constructed with stranded oxygen-free copper conductors and flame-retardant industrial PVC outer sheath, the cable supports repeated bending during cabinet wiring layout without internal core fracture. DCS system integrators, plant instrumentation maintenance engineers and process control technicians gain practical value from its precision-matched 36-pin pinout that fully aligns with original Yokogawa ESB port definitions, vibration-resistant metal locking plugs that prevent loose contact from cabinet thermal expansion and mechanical shaking, and pre-assembled structure that eliminates manual crimping and soldering errors on site. This standardized bus cable ensures seamless redundant controller switching and stable 24/7 continuous operation for critical process control and safety instrumented loops in heavy industrial facilities.
