The ABB SCYC51050 Cyclofibre optical cable features superior electromagnetic compatibility. Signal transmission relies on light instead of electric signals, so the cable is fully resistant to electromagnetic interference, radio frequency interference and magnetic coupling effects. It is not susceptible to noise interference from surrounding VFDs, high-current power cables, contactors and welding devices.

It produces no electromagnetic radiation and will not create crosstalk with neighboring signal cables, effectively avoiding EMI emission risks. It offers dependable galvanic isolation between transmitters and receivers, eliminating ground loops that frequently lead to signal distortion within industrial drive systems.

Its reliable EMC capability suits high-noise industrial settings including ABB drive cabinets with intensive high dv/dt and switching noise. Additional shielding or EMC suppression parts are unnecessary for this cable. It sustains stable optical communication without signal deviation or data loss, even when laid in parallel with high-power cables.

FAQ for ABB SCYC51050 CycloFibre Optical Fiber Cable

Q: What is ABB SCYC51050?

A: ABB SCYC51050 is a proprietary CycloFibre optical fiber cable designed for optical communication between ABB drive control boards and power modules. It provides galvanically isolated signal transmission and strong anti-interference performance inside high-power drive cabinets.

Q: Which ABB drives is SCYC51050 compatible with?

A: It is specially used for ABB ACS800 series inverter systems, matching CycloFibre optical ports on control units and power units.

Q: What is the advantage of CycloFibre link using SCYC51050?

A: Optical transmission completely isolates electromagnetic noise generated by IGBT switching, avoiding signal distortion and communication dropout in high EMI environments.

Q: Can I replace SCYC51050 with a normal generic fiber cable?

A: Not recommended. It uses ABB dedicated CycloFibre optical specification. Standard multimode fiber cannot guarantee stable communication link.

Q: What should I notice during installation of SCYC51050?

A: Do not bend the cable below the minimum bend radius. Avoid pulling, twisting or scratching the fiber end face, and keep the optical connector clean.

Q: Is ABB SCYC51050 discontinued?

A: Yes, this is an obsolete ABB spare part. We supply original surplus stock for ACS800 system maintenance and replacement projects.

Q: What industries use ABB SCYC51050?

A: Widely applied in metal rolling, pulp & paper, mining, chemical plants and power stations equipped with ABB ACS800 large drives.
