Monitor di velocità
SAFEONE DN3PD2
Il SAFEONE DN3PD2 è un dispositivo di commutazione di sicurezza per il monitoraggio della velocità senza sensori di motori trifase e monofase. La velocità viene rilevata misurando la frequenza del campo rotante effettivo del motore. Il modulo viene parametrizzato tramite l'intuitivo software GO:BEYOND e soddisfa il livello di prestazioni certificato e o SIL 3.
Senza sensore
Si adatta a qualsiasi quadro elettrico
Configurabile con il software
