Övervakningsmodul för jordfel

Med den nya signalmodulen för jordmotstånd i det jordade driftläget erbjuder WAGO inte bara detektering av 0 V-jord, utan även helautomatisk detektering av motståndsvärden under ett icke-justerbart, obalanserat isolationsmotstånd mellan jord och +24 V eller 0 V av matningsspänningen.

Jordfelsindikator – Automatisk testning av isolationsmotstånd

Jordfelsindikatorn erbjuder branschens bästa kostnads-nyttoförhållande och är lätt att använda. Byte av jordfelsindikatorns anslutning är enkelt Endast två extra kablar behöver anslutas till PLCn för att göra den potentialfria kontakten redo för utvärdering.

Fördelar med jordfelsindikatorn jämfört med mekanisk jordledaranslutning – i praktiken

  • Manuell testning för uppkommande jordfel ersatt av helautomatisk övervakning
  • Minskning av inspektionsintervallet från ca. 3 månader till 10 sekunder
  • Omedelbar signalering genom potentialfri kontakt till PLCn
