YCB301-C300 ESB Bus Cable | Yokogawa

Configured for ESB bus interconnection in Yokogawa DCS networks, the Yokogawa YCB301-C300 (YCB301 ESB Bus Cable) provides direct physical connection between compatible ESB bus node units, node adapters, and Field Control Units. The YCB301-C300 uses 36-pin connectors at both cable ends and provides a specified cable length of 3 m for supported Yokogawa FIO control environments.

Hardware Specifications

Yokogawa DCS Process Control Connectivity

The YCB301-C300 provides a physical communication path within Yokogawa ESB bus architectures used by distributed control and safety-related systems. Unlike field instrument cables carrying 4-20 mA HART signals, this cable supports the system-level ESB communication infrastructure between compatible hardware components.

Therefore, installation must maintain correct connector orientation and approved system topology. The cable route should also remain separated from high-power conductors where electromagnetic interference could affect communication integrity.

Frequently Asked Questions

Q: What is the physical connector configuration of the YCB301-C300?
A: The YCB301-C300 uses 36-pin connectors on both ends for connection to compatible Yokogawa ESB bus hardware.

Q: Does the YCB301-C300 require an external power supply?
A: No separate power consumption is specified because the product functions as a passive ESB bus interconnection cable.

Q: Can the YCB301-C300 be extended beyond its 3 m length using additional cables?
A: Any additional cable arrangement must comply with the applicable Yokogawa ESB bus topology and cumulative transmission distance requirements. Do not exceed system configuration limits.

Field Installation Guidelines

• Verify that all connected equipment supports the YCB301 ESB bus cable interface before installation.
• Confirm the required cable length and connector orientation before connecting both 36-pin ends.
• Disconnect or isolate equipment according to applicable system maintenance procedures before handling bus connectors.
• Route the cable separately from high-voltage power wiring and sources of electromagnetic interference.
• Avoid excessive bending, twisting, crushing, or mechanical tension on the cable assembly.
• Secure the cable to prevent movement or connector stress during equipment operation.
• Do not modify the connector assembly or cable length unless the system engineering documentation explicitly permits the change.
• Verify the complete ESB bus topology after installation and before returning the control system to service.
