Operation Theorem
The isolated digital output circuits are as following. The output is open
collector type. The isolation voltage between the isolated output and
the host power signals is 5000 Vrms.
4.5 Isolated Digital Input
The isolated digital input circuits are as following. The input is
equipped with current-limit resistor. The input voltage could up to 34V.
The isolation voltage between the isolated input and the host power
signals is 5000 Vrms.
