Characteristics of the inputs/outputs
Outputs
■
Semi-conductor outputs (high side), short-circuit and overload protection
Channels 1...8
switching voltage
10...32 V DC
can be configured as ...
switching current
max. 4 A (with/without current monitoring)
total current
max. 16 A
The current measurement of 2 channels each can be selected by means of the wire
connections. The following channels are combined: 1+2, 3+4, 5+6, 7+8.
■
PWM outputs
Two outputs each are combined (1+2, 3+4, 5+6, 7+8).
The output signal is present at only one of the two outputs while the other output is
OFF (e.g. left/right or up/down functions).
It is possible to immediately switch over from one output to the other.
PWM frequency
20...250 Hz
pulse/break ratio
0 ‰; 50...1000 ‰
resolution
1 ‰
switching current
max. 4 A (referred to PWM value 1000‰)
With smaller PWM values this current value is reduced.
value range
-1000...+1000 ‰
Values > +1000‰ are internally rounded to +1000 ‰.
Values < -1000‰ are internally rounded to -1000‰.
With the values between -50...+50 ‰ the output is switched off.
value output
+50...+1000‰ are present at the odd-numbered outputs
(channels 1, 3, 5, 7)
-1000...-50‰ are present at the even-numbered outputs
(channels 2, 4, 6, 8)
■
Current outputs
With the configuration as "current-controlled output" two outputs each are
combined (1+2, 3+4, 5+6, 7+8).
PWM frequency
20...250 Hz
control range
20...1000 mA / 80...4000 mA (see control parameters)
control characteristics can be set via the object directory (see control parameters)
setting resolution
1 mA
precision
± 2% FS
switching current
max. 4 A
load resistance
min. 3/12
Ω
(at U
B
= 12 V DC)
min. 6/24
Ω
(at U
B
= 24 V DC)
value range
-4000...+4000 mA
Values > +4000 mA are rounded to +4000mA.
Values < -4000 mA are rounded to -4000mA.
Values -80...+80 mA are interpreted as "OFF".
value output
80...4000 mA are present at the odd-numbered channels (1, 3, 5, 7)
-4000...-80 mA are present at the even-numbered channels
(2, 4, 6, 8)
Digital and PWM/current output can be combined to one connection pair, i.e. one
output acts as binary, the other output as PWM/current output.
The outputs can then be switched separately from each other.
Control parameters
By indicating the max. load current [mA] for each output pair the respective control or
value range (1000 or 4000mA) is selected automatically.
In addition the P/I behaviour of the current control function for each output pair can
be parameterised.
Free-wheel diode is integrated!
To avoid a falsification of the measuring result, no external free-wheel diode must be
connected in parallel with the load in the "current-controlled output" operating mode.
Inputs
■
Binary inputs, for positive sensor signals (low side)
Channels 9...12
switch-on level
0.4...0.7 U
B
can be configured as ...
switch-off level
0.2...0.24 U
B
input resistance
3 k
Ω
input frequency
50 Hz
■
Node ID selector
Each input can be allotted a value between 2
0
and 2
3
. The resulting numerical value
is added to the basic node ID according to the input and the value.
If inputs are configured as node ID selector, the module does not go into the PRE-
OPERATIONAL status after switch-on before a valid signal (”0” or ”1”) has been
present at the selector inputs for at least 500ms and the resulting node ID has been
received.
It must be possible to clearly assign the value of the node ID selector to the inputs,
i.e. the inputs must have different values!
