1.5.6 Pin Assignment X4 Parallel Outputs
Open-collector-outputs, which switch the positive potential, are used as parallel
outputs. These outputs are suitable for direct control of PLC inputs. The outputs
can be activated by means of function keys or the controller. The assignment of
these functions is carried out in the programming software. The parallel outputs are
designed for use in standard mode only.
Technical Data:
Input voltage
24VDC in accordance with EN61131-2
Output Current max. 0.2 A
The outputs are short-circuit-proof!
The voltage supply must be provided externally. Pins 9 through 13 for the negative
potential are connected internally.
Connector in the operating terminal: 15-pin SubminD male connector strip

1.6 Shield
The shield must be connected to the metal hoods of the connector housings at both
ends and over as large a surface as possible. It should be noted that a potential
equalization line with a minimum cross-section equal to 10 times that of the shield
may be necessary as a result of the grounding on both sides.
