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
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
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
min. 12 / 3 Ω (at U
Load resistance
min. 24 / 6 Ω (at U
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 diodes for the deactivation of inductive loads are integrated
