1. Description
The NG4 p ower supply supplies regulated direct voltage s for
supply ing power to the re spective devices of the prod uct family of I/O
compon ents. T he device supplies regulated dire ct voltage 24 V DC at
a power o f 16 watt s. A parallel op eration of se veral power su pply units
is not allo wed. The secondary vol tage can only be tapped at the right
side of the plug connector and at the screw-type terminals on th e top
of the module. The bus communic ation is lo oped through on both
sides of the plug connectors.

• T he modul e can be ali gned without interspace. Use the jumper
plug to connect b us and supply voltage when the module s are
mounte d in series.
• T he maximum quanti ty of modules connecte d in line is limited
to 15 or to a maximum power co nsumption of 2 Amps ( AC or
DC) per connec tion to the power sup ply. For any s imilar block of
additi onal modules a sep arate connecti on to the power suppl y is
