Material Composition: Board substrate: FR-4 glass fiber epoxy printed circuit board. Signal connectors: gold-plated copper alloy pins. Sampling components are high-precision industrial resistors and capacitors. Protection components are high-voltage transient suppression devices. Board fixing brackets use reinforced engineering plastic.
Structural Features: Flat rectangular printed circuit board structure. Multi-group pin connectors arranged on board edge for power, signal and communication wiring. Components arranged on top surface of PCB. Fixed installation holes at four corners of board. Isolation area layout separates high voltage power signal area and low voltage control signal area.
Working Principle: The board obtains 24 VDC control power. It samples voltage and current signals from power circuit through sampling circuit. Internal processor executes control algorithm according to set parameters. It generates drive pulse signal to control power semiconductor switching action. It continuously monitors temperature and current. When fault condition occurs, it immediately blocks drive pulse and records fault information.
Installation Requirements: Fix board on designated installation position of equipment chassis with screws. Keep isolation area layout unchanged. Reserve air circulation space around board. Separate high voltage wiring and low voltage signal wiring. Cut off all power supply before board installation or removal.
Precautions for Use: High voltage exists on matched power circuit, strictly follow lockout-tagout procedure. Wear anti-static wristband before touching PCB. Do not scratch copper foil and solder pad on board. Regularly check connector tightness. Replace board immediately if sampling signal drift exceeds specification.
