Inputs and outputs
General
All outputs are electrically isolated from each other and from all other circuits.
All operating data and output values can be adjusted.
Description of used abbreviations U
ext
= external voltage; R
L
= load + resistance;
U
o
= terminal voltage; I
nom
= nominal current
Safety limit values (Ex i):
U
i
= max. input voltage; I
i
= max. input current; P
i
= max. input power rating; C
i
=
max. input capacity; L
i
= max. input inductivity
