January 2012 3.10 Power Supply for PLC Outputs 215
Rated operating
current per output
UxC 11x: 0.150 A
PLD-H xx-xx-xx: 2 A
Simultaneity with a supply voltage of 25.4 V:
2 outputs with 4 A each
4 outputs with 2 A each
8 outputs with 1 A each
Total current:
Out0 to Out7: ≤ 8 A
Out0 to Out3: ≤ 4 A
Out4 to Out7: ≤ 4 A
For all PLD-H xx-xx-xx units, it must be remembered that a total current of
max. 8 A per slot (PLD-H) must not be exceeded! This applies regardless of
the number of outputs of the PLD-H. With the UxC 11x, a total current of 1.2 A
for the eight outputs of a connector must not be exceeded.
In the event of an overload or short circuit and as a consequence of excessive
temperature, the individual PLC outputs of a PLD or UxC switch off automati-
cally. Then the outputs will try to switch on again cyclically.
Furthermore, the modules have a fuse that prevents an excessive total current
per output module with eight outputs (> 8 A not self-healing on PLD, > 1.2 A
self-healing on UxC) and thus destruction of the modules.
