Voltage supply only for measuring devices, not to be used for drives or similar sources of impulse interference at the
same time.
MICRO-EPSILON recommends using the optionally available PS2020 power supply,
, for the sensor.
5.4.4
Analog output
The sensor produces a current output of 4 ... 20 mA
i
The output may not be used continuously in short-circuit operation without a load resistor.
Continuous short-circuit operation leads to thermal overloading and thus causes the output to switch off automati-
cally.
Connect the
D

J (purple)
