Characteristics of the inputs / outputs
Inputs
Channels 1...4, channels 9...12
• 8 inputs for positive sensor signals
For each input the pins +U
B
and Bin INx are available
Channels 7...8, channels 15...16
• 4 inputs for positive sensor signals
Can be used as an alternative to the 4 outputs.
For input and output one pin is available (double configuration).
The inputs can be used to read back the output signals.
Current consumption
I
IN
= 4 mA
(for U
B
= 10 V)
I
IN
= 17 mA
(for U
B
= 30 V)
Switching threshholds
HIGH = 8 V
LOW = 2.5 V
Switching frequency
25 Hz max.
(for ti = tp)
Channels 5...6, channels 13...14
• 4 inputs, to be configured via CANopen:
for ratiometric measurement for potentiometric transducers (e.g. joystick)
For each input the pins +U
B
, Ana INx and GND are available
Input resistance
typ. 50 k
Ω
Resolution based on 1/2 supply voltage U
B
= ± 200 steps (for U
B
= 12 V), ± 400 steps (for U
B
= 24 V)
for absolute value measurement 0...10 V
For each input the pins Ana INx and GND are available

typ. 50 k
Ω
Resolution
8 bits
Accuracy
typ. ± 2 LSB
as binary inputs
For each input the pins +U
B
and Bin INx are available
Input resistance
typ. 50 k
Ω
Switching threshhold at 1/2 supply voltage U
B
Outputs
Channels 7, 15
• 2 positive-switching outputs; short-circuit and overload protected;
the supply voltage U
B
is switched without additional fuse.
The output states can be read back (see inputs).
For each input the pins Bin OUTx and GND are available.
When inductive loads are switched, free-wheeling diodes must be connected in
parallel with the load!
Switching current
max. 500 mA
Channels 8, 16
• 2 PWM outputs (high side), variable frequency
PWM frequency
20...250 Hz
Pulse duty factor
0...1000 ‰
Resolution
1 ‰
Switching current
max. 500 mA
