Properties of the digital inputs
The digital inputs of the digital on-board I/O module have the following properties:
Property
Description
Additional information
Standard and high-speed
inputs
The digital on-board I/O module has 32 high-speed
inputs for signals up to a max. of 100 kHz. The inputs
can be used as standard inputs and as inputs for tech-
nology functions.
The inputs have a rated input voltage of 24 V DC.
The inputs are suitable for switches and 2-/3-/4-wire
proximity switches.
Section Wiring (Page 77)
Configurable diagnostics
The digital on-board I/O module is able to diagnose
errors. The module reports the diagnosed state to the
CPU using a diagnostics error interrupt. You can pa-
rameterize the type of diagnostics channel-specifically.
Section Parameters of the digital on-
board I/O (Page 125)
Hardware interrupt
You can react to process events (such as positive
edge, negative edge) through the configuration of a
hardware interrupt. Hardware interrupts can be parame-
terized channel-granularly.

outputs (Page 111)
Standard and high-speed outputs
Standard outputs The digital on-board I/O module has 16 standard out-
puts.
Section Wiring (Page 77)
High-speed outputs Of the 32 standard outputs you can also use 8 outputs
as high-speed outputs for technology functions.
Rated output voltage
The outputs have a rated output voltage of 24 V DC.
Output frequencies and
output currents
Rated output current as output for standard mode:
0.5 A per channel.
As an output for technology functions, you can select
between an output current of up to 0.5 A at an output
frequency up to 10 kHz (load dependent) and a re-
duced output current of max. 0.1 A at an increased
output frequency of up to 100 kHz.
