Electrical Connections

The terminal screws should be tightened with a slotted screwdriver (blade width 2mm).

DC Power Supply

The unit accepts DC supply from 18 to 30 V at the terminals 1 and 2. The power consumption depends
on the level of the supply voltage with approx. 100 mA and the additional current required at the
Auxiliary Voltage Output.

All GND terminals are internally interconnected.

Auxiliary Voltage Output

Terminal 3 and 4 provide an auxiliary output for supply of sensors and encoders.
The 24 VDC output voltage depends on the power supply (see Technical data).
The auxiliary voltage output is switchable from 24 VDC to 5 VDC.

7388_5150_06a_oi_e.docx / Jan-21 Page 11 / 66

SSI-Inputs

At Terminal 5, 6, 7 and 8, the connection is available for SSI signals. The basic settings must be set in
the menu SSI PROPERTIES.

Control Inputs

The three control inputs at terminal 10, 11 and 12 have HTL PNP characteristics.
In the COMMAND MENU the programmable functions for the control inputs can be assigned.
Available functions are: reset the display value, display switching, locking the touch screen or release
the lock function of the control or relay outputs.

Wiring of the control inputs:

Unconnected PNP inputs are always “LOW”.
All inputs are designed to receive impulses from electrical impulse sources.

Notice for mechanical switching contacts:
When exceptionally mechanical contacts are used, please connect an external capacitor between
GND (-) and the corresponding input (+). A capacity of 10 µF will reduce the input frequency to
20 Hz and miscounting due to contact bouncing will be eliminated.

Analog Output (Option AO/AR)

A 16 bit analog output is available at terminal 13 and 14 / 15
This output can be configured and scaled in the ANALOG MENU.

The following configuration is possible:

• Voltage output: -10 … +10 V

• Current output: 0 … 20 mA

• Current output: 4 … 20 mA

The analog output is proportional to the display value and is referenced to potential AGND.
AGND and GND are internally interconnected.

Important:
A parallel operation with voltage and current output at the analog output is not allowed.
