Certificazione SIL3 e architettura TMR
Il modulo è progettato per sistemi strumentati di sicurezza certificati SIL3. La sua architettura TMR (ridondanza modulare tripla) 2oo3 garantisce l'esecuzione in stato sicuro in condizioni di guasto. L'isolamento galvanico tra i canali e il comune di campo offre una solida protezione contro i disturbi elettrici, mentre il monitoraggio opzionale della linea migliora la copertura diagnostica.
Domande frequenti
D: Il modulo supporta la sostituzione a caldo? R: No. L'alimentazione deve essere isolata prima della rimozione o dell'inserimento per mantenere l'integrità del sistema.
D: Qual è il ritardo di commutazione della ridondanza? R: La commutazione tra sezioni ridondanti avviene entro il ciclo del sistema, in genere in meno di 0,5 ms, il tempo di aggiornamento.
D: Con quale frequenza deve essere eseguita la calibrazione? R: Si raccomanda un intervallo di 2 anni per i controlli di calibrazione dei canali di ingresso.
Linee guida per l'installazione sul campo
Assicurarsi che siano presenti fusibili esterni ove richiesto, poiché il modulo non dispone di fusibili interni.
Mantenere i cavi schermati con una messa a terra adeguata per ridurre al minimo la diafonia tra i canali.
Rispettare le specifiche ambientali (Documento 552517) per i limiti di umidità e temperatura.
Verificare che le barriere di sicurezza intrinseca esterne siano installate quando si opera in zone pericolose.
Consentire un flusso d'aria adeguato attorno al modulo per dissipare un consumo energetico di 15–18 W.
