Technical Specifications Multi‑channel driving signal 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. Conformal coating on PCB surface.
Functional Features Receives control signals from main control board and completes isolation and driving amplification. Distributes driving signals to each DC power functional unit. Collects temperature, fault and running status feedback signals from power modules. Converts feedback signal level and forwards data to main controller. Executes hardware channel fault diagnosis.
Application Scenarios Spare replacement circuit board for GE DC power conversion and drive equipment. Applied for maintenance work in power and metallurgy industrial sites.
Performance Parameters Accurate driving signal transmission timing performance, reliable galvanic isolation capacity, stable multi‑channel status signal acquisition capability.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Signal driving circuit, opto‑isolation assemblies, signal conditioning peripheral components. Multi‑pin plug‑in connectors, metal screw mounting hardware. Conformal protective coating layer.
Structural Characteristics Rectangular PCB structure. Main‑controller‑side connectors and power‑unit‑side connectors are distributed on different edges. Pre‑drilled mounting holes for cabinet bracket installation. Clear isolation boundary divides PCB into low‑voltage logic zone and power signal zone.
Working Principle Auxiliary DC power feeds whole board circuit. Control commands from main controller go through isolation and driving circuit and send to DC power units.
Installation RequirementsFasten circuit board to cabinet mounting bracket with screws. Fully insert and lock all plug‑in connectors. Restore auxiliary power, carry out driving signal test and status feedback verification.
Usage Notes Comply with high‑voltage safety operation specifications. Avoid scratching conformal coating protective layer.
