DIGITAL INTERFACE X7
For the connection of the safety circuits and for external control, the device
has a 25-pin connector X7.
Note:
The inputs and outputs described in the following are connected
to X7 in the standard device. Additional digital outputs can be purchased
as an option.
Note:
To activate the digital inputs, a voltage of +5...24V DC must be ap-
plied. For this purpose you can apply the +24V (+Ue) control voltage on
pin 22. Ground is pin 17 (GNDE).
Auxiliary vUe:
This floating control voltage makes it possible for the user to control the
device via the digital interface without the need to connect an external
power supply.
Note:
The maximum load including the outputs should not exceed 300mA.
Pin 22
+Ue
(24V/0.3A)
Pin 17
GND
(reference potential)
Safety circuit „SK1“:
If this pin is connected to +Ue (pin 22) or an external power supply, SK1
is closed. In the case of operation in a test system the circuit is closed by
a safety switch that is actuated when the guard is closed.
Pin 21
SK1
Safety circuit SK2
Pin 15
SK2 (default) -
If this pin is connected to GND
(pin 17) SK2 is closed ( negative switching).
Pin 16
SK2 -
Using internal jumpers, SK2 can be
changed to +“positive switching“. SK2 is then closed by making a
connection between pin 16 and +24 V DC (pin 22)..
6.2.5.1 OUTPUTS
The digital outputs are designed for „positive switching“, for 24V/ approx.
50mA. The reference potential in this case is also GND.
