Power Supply
The unit does not possess its own power supply unit. It must be supplied by an external source
with +5 VDC +/-10% (approx. 50mA), which can either be connected to the 9-position output
connector or the screw terminals marked “GND” and “5V” (see connection diagram below).
Pin 4 of the output connector is internally connected to the +5V screw terminal.
Also, Pin 4 of the input connector is on same potential as the +24V screw terminal.
This enables the user to externally supply an encoder system via the Sub- D- connector without
necessity to split the 9- wire cable.
The +24V*) screw terminal serves as encoder supply only and does not affect the operation of
the unit.
The 5 VDC unit supply is protected against wrong polarity by a diode and a fuse.
