Product Introduction
The YCB301-C020 is a Yokogawa ESB bus cable with a 20 cm length and 36-pin male-to-male connectors. It is designed for ESB bus communication within Yokogawa distributed control systems, enabling reliable data transmission between controllers, I/O modules, and other system components.
As the shortest variant in the YCB301 family, the C020 is commonly used for tight-space installations, rack-internal connections, or applications where minimal cable slack is preferred. For maintenance and procurement teams, it is a direct-fit replacement for existing YCB301-C020 cables in Yokogawa DCS/PLC cabinets.
QA & Testing SOP
- Label verification: Confirm Yokogawa branding, full part number YCB301-C020, and length marking.
- Visual inspection: Check cable jacket, connector shells, and strain relief for damage, corrosion, or deformation.
- Connector pin check: Inspect all 36 pins on both ends for bent pins, oxidation, or loose contacts.
- Continuity test: Verify pin-to-pin continuity and absence of shorts across the cable.
- Length confirmation: Confirm the cable measures approximately 20 cm end-to-end.
- ESD-safe packing: Ship with connector caps and anti-static packaging, plus label photos for receiving QA.
Installation Pitfalls & Guide
❗ Confirm the cable length before ordering. The YCB301 family includes multiple lengths (C020 = 20 cm, C100 = 1 m, C200 = 2 m, C300 = 3 m, C400 = 4 m, C800 = 8 m). Substituting the wrong length can cause routing issues in tight cabinets.
❗ Verify connector compatibility. The YCB301-C020 uses 36-pin male connectors. Ensure both connected devices accept this connector type.
❗ Do not force connectors. ESB bus connectors must seat cleanly. Forcing can bend pins and damage the backplane or module port.
❗ Route away from high-voltage cables. Keep ESB bus cables separated from power cables to minimize electromagnetic interference.
Replacement steps:
- Pre-install: Confirm the existing cable part number, length, and routing path.
- Isolate system: Follow plant MOC and control system procedures before disconnecting live bus cables.
- Replace cable: Disconnect the old YCB301-C020 and install the new one, ensuring both connectors are fully seated.
- Commission: Restore power, verify ESB bus communication, and confirm no bus faults on the controller diagnostics.
Technical FAQ
Is pricing flexible? Yes. Price depends on condition, stock availability, and whether the unit is new original or new surplus.
What warranty is included? Surplus cables usually carry a limited functional warranty, often 30–90 days, unless otherwise agreed.
Can replher YCB301 variants? Only if the existing cable is also a YCB301-C020. Other suffixes (C100, C200, C300, etc.) have different lengths and may not fit the same routing.
What systems is it compatible with? It is designed for Yokogawa control systems that use the ESB bus protocol, typically for controller-to-I/O module communication.
Do you provide test records? We can provide label photos, visual inspection notes, and continuity test records.
