Low/High range of signal inputs
The
MRIK3
has a wide-range power supply unit allow-
ing to choose a suitable supply voltage. The operating
threshold of the signal inputs, however, has to be de-
fined by taking the supply voltage into account. The fol-
lowing two different operating thresholds can be ad-
justed:
•
Low-range treshold U
AN
≥
10 V; U
AB
≤
8 V
(code jumper plugged)
•
High-range treshold U
AN
≥
70 V; U
AB
≤
60 V
(code jumper not plugged)
