Number of digital inputs/outputs 4
●
Max. 4 as measuring input inputs

If used as an input:
● Input voltage, rated value 24 V DC
● Input voltage, for signal "1" 15 … 30 V

2)
-3 … +5 V
Galvanic isolation no
Current consumption typ. at signal level "1" 9 mA at 24 V
Input delay, typical (hardware) Signal "0" → "1": 5 µs
Signal "1" → "0": 50 µs

The digital inputs are protected against polarity reversal up to -30 V
Max. switching frequency of the DO
The
max. switching frequency of the hardware depends on the load. For an ohmic load of 24 V/
0.5 A, it is up to 4 kHz. (typical value; low-high ratio = 50:50; short cable lengths).
Logic control of the digital output is also a limiting factor.
If an X122/X132 DO is set or reset from the user program, no more than 1 edge is possible
per servo or CU sampling time of the inputs/outputs (cu.p0799[0]).
With servo cycles of at least 500 µs, a max. switching frequency of 1 kHz is achieved.
The max. achievable switching frequency can also be limited by the CU parameter p0799[0]
(sampling time of the inputs/outputs of the CU) or p2048 (PROFIdrive PZD sampling time).
