CompactModule Metall CR2031
22
CR2031
Characteristics of the outputs
Digital outputs
8 semiconductor outputs; short-circuit and overload protected
Switching voltage
10...32 V DC
Switching current
max. 4 A
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
With the configuration as "PWM output" two outputs each are combined
(1+2, 3+4, 5+6, 7+8).
PWM frequency
20...250 Hz
Pulse duty factor
50...1000 ‰
Resolution
1 ‰
Switching current
max. 4 A
Total current
max. 16 A
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
Control resolution
1 mA / 4 mA (see control parameters)
Setting resolution
1 mA
Control characteristics can be set via the object directory (see control parameters)
Accuracy
± 2% FS
Switching current
max. 4 A
Load resistance
min. 12 / 3
Ω
(at U
B
= 12 V DC)
min. 24 / 6
Ω
(at U
B
= 24 V DC)
Control parameters
By indicating the max. load current [mA] for each output pair the respective control
or value range (1000 or 4000 mA) is automatically selected.
In addition the P/I behaviour of the current controller can be parameterised for each
output pair.
Free-wheel diode is integrated!
To avoid errors in the measuring result, no external free-wheel diode must be
connected in parallel with the load in the "current-controlled output" operating mode.
