The output voltage of the 24 VDC power supply can be taken from the 4 mm safety sockets mounted on the
front side and additionally supplies the controller and the sensors connected via IO link. The output voltage
is safeguarded with a resettable fuse (4 A).
The energy consumption of the power supply and the power analyzer is determined together with the
"Output 1" connection and measured in the power analyzer with the measuring channel "L1". The energy
consumption of the outputs "Output 2" and "Output 3" is determined separately and measured with the
measurement channels "L2" and "L3".
Only operate the device in an upright position.
