Figure 40: Relay Groups
Inside each group, the relays have just single isolation and thus must be
connected to the same voltage supply. Between the groups, there is a
double isolation and thus the groups can be connected to different
voltage supplies.
Figure 41 displays a typical application of the relay outputs as
connection example.

Note: Relays DO6-DO8 are not hardware interlocked and incidental
energization of more than one relay at the same time might lead to fan
motor damaging.
