The two digital outputs are located at the 15-pin D-Sub-HD male connector of the con‐
necting cable.

NOTE
Provide an arc-suppression switch at the digital output if inductive load is present.
b
Attach a freewheeling diode directly to the load for this purpose.
NOTE
Capacitive loads on the digital outputs have an effect on the switch-on and switch-off
behavior. A maximum capacitance of 100 nF is the limit value.
Function assignment
NOTE
Assign the functions for the digital outputs in the device using a configuration tool, e.g.
the configuration software SOPAS ET.
