Actuator with proportional control
I/O specifications:
Input/Output Specification Comments
Description Easy to use interface with integrated
power electronics (H-bridge).
The actuator is speed controlled by means
of a PWM or 4-20mA signal.
Proportional provides a wide range of pos-
sibilities for customisation.
See connection diagram,
fig. 11, page 33
Brown 12-24VDC + (VCC)
Connect Brown to positive
12V ± 20%
24V ± 10%
12V, current limit 15A
24V, current limit 10A Note: Do not change the power supply
polarity on the brown and blue wires!
Power supply GND (-) is electrically
connected to the housing
If the temperature drops below 0°C,
all current limits will automatically
increase to: 20A for 12V
15A for 24V
Blue 12-24VDC - (GND)
Connect Blue to negative
12V ± 20%
24V ± 10%
