Configured for communication synchronization in CENTUM VP control systems, the YOKOGAWA YCB301-C100 (YCB301 ESB Bus Cable) provides direct physical and electrical execution of ESB bus signal transport between Field Control Units and node units.

Suffix Breakdown & Model Matrix

The YCB301 series utilizes a specific suffix code structure to define cable length requirements for system interconnects:

• Model YCB301: 36-pin to 36-pin ESB bus interconnect cable.
• Suffix C100: Specifies a standard cable length of 1 meter.

Hardware Specifications

Process Control Connectivity and Loop Integrity

The YCB301-C100 cable assembly employs a multi-conductor architecture designed for high-density signal throughput. Each conductor is engineered to support AWG #20 to #24 wire sizes, ensuring low resistance and consistent signal propagation across the ESB Bus network. The cable architecture facilitates channel-to-channel isolation, reducing the risk of induced crosstalk in dense cabinet environments. By maintaining precise impedance characteristics, the cable supports the deterministic timing required for field control unit data exchange. When deployed within the CENTUM VP architecture, the assembly serves as the primary transmission medium, ensuring that 32-channel signal capacity is maintained without attenuation or data packet loss.

Frequently Asked Questions

Q: Does the YCB301-C100 support high-speed data transmission for all node types?

A: Yes. The cable is designed for standard ESB Bus data rates used in CENTUM VP systems, supporting reliable signal transport between FCUs and node units.

Q: Can this cable be trimmed or modified for specific cabinet lengths?

A: The cable is provided as a factory-terminated assembly with 36-pin connectors. Modifying the length or replacing connectors is not recommended as it compromises the factory-certified impedance and shielding integrity.

Field Installation Guidelines

1. Route the YCB301-C100 through cable management trays separated from high-voltage AC cabling to prevent electromagnetic induction.
2. Observe the specified bend radius during installation; excessive tension or sharp bending can damage the internal conductors and connector solder joints.
3. Align the 36-pin connectors with the module interface slots, ensuring the latching mechanisms are fully engaged to provide secure physical contact.
4. Verify pin-to-pin continuity before system startup to ensure no internal wiring faults occurred during cable routing.
5. Secure the cable with strain relief clips at both ends to prevent physical stress on the backplane connectors due to the weight of the assembly.
