3.6 EP3162-0002 - Electrical isolation of the channels
The block diagram shown below illustrates the principle of the electrical isolation of the two channels. The
24V with which the channels are supplied come from an electrically isolated DC/DC and are thus U
A
instead
of U
S
.
Fig.21: Block diagram: electrical isolation
Electrical isolation of GND
The GNDs of channel 1 (GND
A
) and channel 2 (GND
B
) are electrically isolated from each other.
