Technical Specifications Model: GOP1 Input Signal: Electrical logic trigger pulse Output Signal: Optical trigger pulse via optical fiber interface Mounting: Rack plug‑in board Power Supply: Auxiliary control power from cabinet back‑plane Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE
Functional Features Converts electrical trigger pulses into optical pulse signals for fibre‑optic transmission. Complete electrical isolation between control‑side circuit and high‑voltage power unit via optical transmission medium. Front‑panel LED indicators display power‑on status and pulse‑transmitting activity. Built‑in self‑diagnosis monitors internal circuit and optical transmitting component health. Standard optical fiber interfaces support industrial‑grade optical fibre connection.
Application Scenarios Spare‑part replacement for GOP1 optical pulse transmitter board in high‑power rectifier or excitation cabinet. Trigger signal transmission for high‑power thyristor power conversion units. Maintenance and spare‑part renewal for ABB power conversion hardware adopting optical trigger technology.
Working Principle GOP1 obtains auxiliary control power supply from cabinet back‑plane. Electrical trigger pulses sent by main control board enter this board through rear connector. Pulse‑shaping circuit organises signal waveform and drives optical transmitting modules to output standard optical trigger pulses. Optical pulses are transmitted to power unit receiving boards via optical fibre. LED indicators reflect power‑on and pulse‑transmitting real‑time status. On‑board self‑diagnosis continuously monitors hardware working condition and reports fault events.
Installation Requirements Insert GOP1 fully into target cabinet slot and fasten front locking screw. Connect industrial‑grade trigger optical fibres to front‑panel optical interfaces, avoid sharp bending of optical fibre cables. Complete protective earthing complying with power conversion cabinet grounding specification.
