Digital Inputs and Outputs (Terminal Block X0)
The connections No. 7 to No. 10 on Terminal Block X0 can be used as either
inputs or outputs. The configuration is carried out in the Device Configurator.
Depending on the configuration, the technical data corresponds to that of a purely
digital input or output:
Configured as an input:
Input type:
Source operation, electrically connected
Input voltage:
Typ. 24 VDC(15…30 VDC)
Input current:
Typ. 3.6 mA at 24 VDC
Input delay:
Typ. 3 ms
Surge protection:
No
LEDs
No
Connections
Plug-in screw terminal block
Configured as an output:
Short-circuit protection
Yes
Voltage range
24 VDC (12...32 VDC) smoothed
Output current
Max. 0.5 A
Output delay
Typ. 50 µs, max 100 µs at Ohmic load
LEDs
No
Connections
Plug-in screw terminal block

Inputs and outputs
NOTE: Subject terminal block X0
The terminal Uext serves to feed the outputs to terminals 7 ... 10th
If at least I / O 4 ... 7 operated as a receipt, the following must be considered:
If this external supply U ext which outputs the power off and the inputs I / O 4 ...
7 is still tension on the supply voltage of the outputs O 0, ... 3 and I / O 4 ... 7 via
the built-in output transistor of the I / Os diode fed back and would feed the device
connected to the output load.
