Jordmodstandssignalmodul

Med det nye jordmodstand signalmodul, i jordet driftstilstand, tilbyder WAGO ikke kun detektering af 0°V-jording, men også fuldautomatisk detektering af modstandsværdier under en ikke-justerbar, ubalanceret isolations modstand mellem jord og +24°V eller 0°V af forsyningsspændingen.

Egenskaber

Udviklingen af jordmodstands signalmodulet

Enkelt fortrådning

Øjeblikkelig sikring udløses i tilfælde af jordfejl
Øjeblikkelig nedlukning af systemet
Ingen forvarsel

Afbrydelse af jordleder skilleklemme – manuel test af isolationsmodstand

Øjeblikkelig sikring udløses i tilfælde af jordfejl
Øjeblikkelig nedlukning af systemet
Detektering af potentielle jordfejl gennem rutinemæssig manuel vedligeholdelse

Jordmodstandssignalmodul - Automatic Insulation Resistance Testing

Jordmodstandssignal modulet tilbyder branchens bedste cost-benefit-forhold og er let at bruge. Udskiftning af den tidligere jordlederafbrydelsesklemme er ligetil. Der skal kun tilsluttes to ekstra ledninger til PLC'en for at gøre den potentialfri kontakt klar til evaluering.

Fordele ved jordmodstandssignalmodulet i forhold til den mekaniske jordlederafbrydelsesklemmeblok – i praksis

Manuel test for nye jordfejl erstattet af fuldautomatisk overvågning
Reduktion af inspektionsintervallet fra ca. 3 måneder til 10 sekunder
Øjeblikkelig yderligere signalering ved potentialfri kontakt for signalering til PLC

Eksempel på applikationer

Starts sted og resultat

Opgradering fra en jordlederskilleklemme til et jordmodstandssignalmodul

Uanset hvor en jordlederskilleklemme er i brug, kan et jordmodstands signalmodul nemt eftermonteres til fuldautomatisk overvågning.

To 24 VDC strømforsyninger kræver kun en jordmodstandssignalmodul

Selv med to eller flere strømforsyningsenheder forbundet parallelt, en jordmodstandssignalmodul tilstrækkelig til jordfejlsovervågning.
