- Detailed Functional Features
- Arc Suppression Technology
Built-in RC snubber circuit (standard: 100 OH / 0.1 µF) absorbs back EMF from inductive loads at contact break, effectively suppressing arcing and extending contact life by 3-5 volte.
- 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
- Progettazione della sicurezza
Polarity protection prevents damage from reverse power connection
Overcurrent protection guards against output short circuits
Surge voltage suppression protects internal electronic components
- Application Limitations & Note
Load Type Adaptation
Carichi induttivi (motori, elettrovalvole): recommended derating to 50% di valore nominale
Capacitive loads (condensatori, lampade): current-limiting resistor required to prevent inrush current
Specifiche di installazione
Avoid installation near heat sources (> 70 °C)
Maintain at least 5 mm clearance around the module for heat dissipation
Ensure secure wire crimping during wiring to prevent poor contact
Linee guida per la manutenzione
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
