XC77 • XAC77 - Encoder ATEX

Fault connesso a un ingresso del PLC

Fault connesso a un relè



Nessun errore = PLC input basso (0Vdc).
Errore encoder = PLC input alto (+Vdc).

Esempio:

Vdc = +24V
I = 30mA (corrente necessaria per eccitare la

bobina di un piccolo relè)

R2 = 750



Nessun errore = bobina eccitata.
Errore encoder = bobina a riposo.
