Description

WG25 Amplificatore di isolamento di alimentazione | Ingresso 4 ... 20 mA | Ex | Trasmissione di segnali HART

Alimentazione per trasmettitori a 2 fili a sicurezza intrinseca e trasmettitori SMART

  • Nessun alimentatore integrato e quindi costo molto basso
  • Risparmio sui costi grazie alla riduzione dei cablaggi, in quanto non è necessaria l'alimentazione in c.a.
  • Nessuna interferenza con l'alimentazione CA
  • Basso consumo energetico, nessun riscaldamento superfluo della custodia
  • Separazione della protezione secondo la norma EN 61140: protezione del personale di manutenzione e delle apparecchiature successive contro le tensioni eccessive
  • Trasmissione HART®: trasmissione bidirezionale punto-punto di dati digitali secondo la specifica HART®.
  • Soppressione RFI e resistenza alle sovratensioni testate EMC: funzionamento affidabile anche in presenza di interferenze elettromagnetiche
  • Massima affidabilità: nessun intervento di manutenzione e quindi nessun costo associato
  • Garanzia di 5 anni

Ripetitore passivo WG 25 alimentato da loop per l'isolamento di corrente di linee elettriche a 2 fili in aree pericolose e la trasmissione bidirezionale di segnali 4 ... 20 mA e HART®. Con una caduta di tensione di soli 4,2 V, il WG 25 utilizza l'alimentazione in modo ottimale, rendendo collegabili tutti i comuni trasmettitori a 2 fili.

Il prezzo e l'affidabilità sono un chiaro vantaggio rispetto agli alimentatori attivi dei ripetitori. I sistemi multicanale richiedono un solo alimentatore centrale situato in un'area sicura e non necessitano nemmeno di una separazione di protezione.

HART® è un marchio registrato della HART Communications Foundation.
