5.3.3 High−current output module CPX−8DA−H
The high−current output module CPX−8DA−H provides digital
outputs in the valve terminal for connecting current−consum
ing devices with high current consumption (e.g. hydraulic
valves).
Note
Observe the permitted characteristic connection values in
the technical specifications and the temperature de
pendency of the maximum load current as shown in
Fig.A/3, in order to avoid overheating and as a result,
damage to the connections and the electronic module.
Pay attention to the following when planning:
·
Maximum current consumption of 2.1A per output/chan
nel or per output socket when the plug/cable is assigned
twice and maximum current consumption of 8.4A for the
complete module.
·
Note the instructions/footnotes for the relevant sub−base.
·
Note the instructions on contact loading for the relevant
sub−base.
·
Use electric conductors with suitable diameter.
·
Avoid long distances between the load and the high−cur
rent output.
Protection against In addition to a (reversible) electronic short circuit protection
short circuit the output module also possesses an (irreversible) fuse (fus
ible cutout) in case the electronic short circuit protection
device fails.
Note
After the fusible cutout has functioned, the high−current
output module must be replaced.
