Sobre este producto
- 1. Product Parameters Input Voltage: DC 5V ±5% (3.5V–5.5V Range) Current Range: AC 0.3A–5A (±1% Accuracy) Response Frequency: 20Hz–400Hz (50/60Hz Optimized) Output Signal: Relay Switch (NO/NC/COM) Trigger Threshold: Adjustable via Potentiometer (0.3A–5A) Operating Temp.: -40°C to +85°C (Reliable) Relay Contact Rating: 5A@250VAC, 5A@30VDC 2. Key Pin Functions Power & Control VCC: DC 5V Input GND: Power/Signal Ground Relay Terminals COM: Relay Common Terminal (Connect to load power) NC: Normally Closed (Closed when relay disengaged) NO: Normally Open (Closed when relay engaged) ⚠️ Critical Notes: COM-NO/NC max current: 5A (Exceeding causes contact welding) VCC-GND reverse voltage >0.5s damages LM393 comparator 3. Common Issues & Solutions Q1: Relay chatters/noisy operation? Cause: EMI from motors/transformers → Relocate module >10cm away Fix: Add 100nF ceramic capacitor between VCC/GND Q2: Fails to trigger at set threshold? Calibrate: Rotate potentiometer clockwise until relay clicks, then test with 0.5A load Check: Wire diameter ≤5.2mm (thicker wires reduce sensitivity) Q3: False triggers at high temps (>70°C)? Cause: LM393 thermal drift → Recalibrate threshold at operating temperature Mitigation: Add heatsink to LM393 chip (thermal tape recommended) Q4: COM/NC/NO contacts overheat? Verify: Load current ≤5A → Use external relay for >5A loads Upgrade: Replace with silver-alloy contacts (model AGN210)
