3.9.1 Specifications of the outputs
The local digital outputs are supplied by the 24−V logic
voltage (no electrical isolation). They are ESD−protected and
short circuit proof, but do not have
reverse polarity
protection against infeed.
Caution
If 24 V DC voltage is applied and the output pins are used
incorrectly, the device may be seriously damaged.
Therefore:
· Do not apply voltage to the outputs.
· Note the current limitation for the outputs
(max. 1 A permissible per output).
Special features of output 1 (Out1)
 Standard PLC output (active high−side switching)
Special features of output 2 (Out2)
 Differential output (can be pulse−width modulated)
 High− und low−side switching (active full bridge)
 It is not used for controlling a PLC,
but rather for
controlling a load, e.g. to control a pulsed motor brake,
avalve or a fan.
The possible uses dependent on the selected pins are
de
scribed in section 5.6.10.
