詳しい機能特徴
Arc Suppression Technology

RCスナバ回路内蔵 (標準: 100 おお / 0.1 μF) absorbs back EMF from inductive loads at contact break, effectively suppressing arcing and extending contact life by 3-5 回.

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

安全設計

Polarity protection prevents damage from reverse power connection

Overcurrent protection guards against output short circuits

Surge voltage suppression protects internal electronic components

Application Limitations & 注意事項

Load Type Adaptation

誘導負荷 (モーター, 電磁弁): recommended derating to 50% of rated value

Capacitive loads (コンデンサ, ランプ): current-limiting resistor required to prevent inrush current

設置仕様

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

メンテナンスガイドライン

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
