Power Supply
The unit needs a 10 … 30 VDC supply. The level of the supply voltage automatically
determines also the level of the output swing (24 V supply will cause pulse output with 24 V
level also). The supply voltage can either be applied to the screw terminals marked “GND” and
“+24V”, or also via the female SUB-D-9 output connector, using pin 5 (GND) and pin 4 (+24 V).
For encoder supply, an auxiliary voltage of +5 V / 100 mA at pin 4 of the input connector (SUB-
D-9 male) can be made available. This voltage can also be taken from the screw terminal
marked “+5V”.
For use of the +5 V auxiliary voltage at the input connector or the screw terminal, you must set
position 7 and 8 of the 8 pole DIL switch to “ON”.
Warning!
Never, with DIL switch position 7 and 8 “ON“, any external voltage must be
applied to input connector pin 4 or to screw terminal marked “+5V”! This
would cause irrevocable damage to the unit!
