Technical Specifications Multi‑channel pulse output interfaces, multi‑path status signal input interfaces, internal bus connector, auxiliary DC control power supply. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, relative humidity 5%‑95% non‑condensing. PCB surface conformal coating treatment.
Functional Features Receives pulse control signals from main control board and completes isolation and driving amplification. Distributes trigger pulse signals to each power functional unit. Collects fault, temperature and running status feedback signals from power modules. Converts feedback signal level and forwards data to main controller. Supports hardware channel abnormality diagnosis.
Application Scenarios Spare replacement board for GE high‑power rectifier and drive equipment. Used for energy conversion equipment maintenance in power and metallurgical industry.
Performance Parameters Accurate pulse signal transmission timing performance, reliable galvanic isolation capacity, stable multi‑channel status signal acquisition.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Pulse driving circuit, opto‑isolation assemblies, signal conditioning peripheral circuit. Multi‑pin plug‑in connectors, metal screw mounting hardware. Conformal protective coating layer.
Structural Characteristics Rectangular circuit‑board layout. Pre‑drilled mounting holes for cabinet bracket fixation.
Working Principle Auxiliary DC power feeds the whole board. Control pulse commands from main controller go through isolation and driving circuit and send to power units.
Installation Requirements Fasten circuit board to cabinet mounting bracket with screws. Fully insert and lock all plug‑in connectors. Restore auxiliary power, carry out pulse signal simulation test and status feedback test.
Usage Notes Strictly observe high‑voltage safety operation regulations. Anti‑static protection cannot be omitted. Hot‑swap under powered state is prohibited. Avoid mechanical scratch to conformal coating.
