- Detailed Functional Features
- Arc Suppression Technology
Built-in RC snubber circuit (기준: 100 오 / 0.1 μF) absorbs back EMF from inductive loads at contact break, effectively suppressing arcing and extending contact life by 3-5 타임스.
- Status Monitoring System
Red LED provides real-time module status indication
Simple fault diagnosis: LED off = power fault; LED on but no contact action = internal circuit fault
- 안전설계
Polarity protection prevents damage from reverse power connection
Overcurrent protection guards against output short circuits
Surge voltage suppression protects internal electronic components
- Application Limitations & 메모
Load Type Adaptation
Inductive loads (모터, solenoid valves): recommended derating to 50% of rated value
Capacitive loads (capacitors, lamps): current-limiting resistor required to prevent inrush current
설치사양
Avoid installation near heat sources (> 70 ℃)
Maintain at least 5 mm clearance around the module for heat dissipation
Ensure secure wire crimping during wiring to prevent poor contact
유지 관리 지침
Regularly check LED status and terminal tightness
Insulation test recommended every 6 months in harsh environments
Replace the entire module if faulty; internal repair is not recommended
