2.8 to 6A
1)
A supply group always consists of two adjacent
channels starting with channel 0. Channels 0 and 1, 2
and 3 and so on up to 14 and 15 therefore form one
supply group.
2)
Following a short circuit, reclosing under a full load is
not guaranteed. To prevent this, you can do one of the
following things:
Change the signal at the output
Interrupt the load voltage of the module, or
Briefly disconnect the load from the output
