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, 솔레노이드 밸브): recommended derating to 50% 정격 가치의

Capacitive loads (커패시터, 램프): 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
