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 inputs are available� The
configuration (voltage input or current input) is set in the IN 1 / IN 2 Properties
menus�
The configuration (voltage input or current input) has to be set before
connecting the sensor�
Connection of the analogue inputs:

Current input
7.4 Control inputs
On terminals 10, 11 and 12, three control inputs with HTL-PNP characteristic are
available�
These inputs can be configured in the COMMAND MENU and are used for
functions that can be triggered externally such as resetting the display value,
changing the display, locking buttons of the touch screen or releasing the latching
of control outputs�
