Core Functions

1. Optical‑Electrical Signal Conversion for Real‑time Drive Communication This board implements bidirectional conversion between electrical logic signals and optical fiber signals. It transmits high‑speed real‑time control pulses, drive setpoint commands, inverter status feedback, current‑voltage monitoring data and fault alarm signals between main controller unit and power‑unit stacks via fiber links. Optical transmission eliminates ground‑loop interference and high‑voltage surge crosstalk inside high‑power converter cabinets.More products: www.plcva.com

1. Galvanic Isolation Between Control Logic and High‑Power Power Stage Fiber‑optic physical isolation separates low‑voltage control circuits from high‑voltage power electronics section. It protects sensitive control logic circuits from EMI, high‑voltage spikes and noise generated by IGBT power modules in medium‑voltage variable‑frequency drives. This isolation greatly improves system stability under heavy‑interference industrial‑site conditions.
2. Hardware‑level Link Diagnosis & Fault Monitoring On‑board hardware logic continuously monitors optical‑link health, signal loss, communication timeout and frame errors. It detects fiber cable breakage, link attenuation and board hardware failures. Status LED indicators show power‑on status, optical‑link activity and fault codes for quick on‑site troubleshooting. Detected faults will be uploaded to the main drive controller and trigger system interlock protection.

GE CONVERTEAM PIB‑314C Optical Interface Card

1. Backplane Bus Data Interaction with Main Control Unit Installed as a plug‑in VME‑format board inside the ALSPA drive control cabinet. It communicates with drive CPU through system backplane bus, completing command distribution and status‑data collection. It acts as the critical intermediate bridge between master control board and power‑unit optical‑communication chain.
2. Industrial‑grade Rugged Hardware Performance Industrial conformal‑coated PCB design, wide operating temperature range, anti‑vibration and anti‑shock capability for heavy‑duty power‑conversion equipment. Designed for long‑term continuous operation; it serves as spare‑part replacement for existing running drive systems.plcva.com
3. Proprietary Real‑time Drive‑specific Communication It works with Converteam/GE ALSPA medium‑voltage drive proprietary fiber protocol, not general‑purpose Ethernet. It guarantees low‑latency deterministic transmission required for high‑power motor closed‑loop vector control.
