Both analog inputs can be configured as supplementary digital inputs if an additional function is required.
Switching thresholds:
0 1: Rated voltage 2 V
1 0: Rated voltage 0.8 V
Analog inputs are protected against inputs in a voltage range of ! 30 V and have a common-mode voltage in
the ! 15 V range.
Analog outputs
2 2 2 2 2 2
Analog outputs have short-circuit protection, but are not isolated. Maximum output voltage = 10 V in current
mode,
maximum output current = 20 mA in voltage mode.
The reaction time should equal approximately 1 ms with a load of maximum 10 k" in voltage mode.
