Funzione

Questo condizionatore di segnale monitora la condizione di sovravelocità o sottovelocità di un segnale digitale (sensore NAMUR/contatto meccanico) confrontando la frequenza di ingresso con la frequenza di riferimento programmata dall'utente.

Una condizione di sovravelocità o sottovelocità è segnalata attraverso le uscite relè. Il rilevamento dei guasti delle linee del circuito di campo è indicato da un LED rosso, dal Power Rail e da un relè. La funzione di esclusione all'avvio imposta le uscite relè alle condizioni predefinite programmate dall'utente fino a un massimo di 1.000 secondi.

È possibile la semplice programmazione dell'unità tramite una tastiera posizionata sulla parte anteriore.

In caso di utilizzo con il sistema Power Rail, sono disponibili messaggi di errore collettivi come funzione esclusiva.

Per informazioni aggiuntive, consultare il manuale e visitare il sito Web www.pepperl-fuchs.com.
