7.1 DC voltage supply
The device can be supplied with direct voltage between 18 and 30 V DC via the
terminals 1 and 2� The current consumption depends, among other things, on the
level of the supply voltage and the setting and is typically at approx� 100 mA plus
the sensor current consumed at the auxiliary voltage output�
All GND connections are internally connected with each other�
7.2 Auxiliary voltage output
Auxiliary voltage for sensor supply is provided at terminals 3 and 4�
The output voltage depends on the device supply:
● In case of DC device supply, the output voltage is approx� 1 V less than the
supply voltage applied at terminals 1 and 2 and the max� load must not exceed
250 mA�
● In case of AC device supply, the output voltage is 24 VDC (± 15%) and the
max� load must not exceed 150 mA at temperatures up to 45 °C� At higher
temperatures the max� output current is reduced to 80 mA�
7.3 Analogue inputs
On terminal 5, the reference potential (AGND) for the analogue inputs is
connected� On terminals 6 and 7, two 16 bit analogue outputs are available� The
configuration (voltage input or current input) is set in the IN 1 / IN 2 Properties
menus�
NOTE
Important: The configuration (voltage input or current input) has to be set before
connecting the sensor�
