With current input max. 10A
Example: Typical examples are actuators from GAC, Woodward Flowtech ITB.
It is electro-magnetic actuator with a strong return spring. This is in principle electromagnet with proportional
characteristic – the bigger is the current to the actuator, the bigger is the angle of the actuator. The polarity of the
current is not important. This type of actuator can be with or without position feedback. For this actuator choose
option ActType: Wiring: LINEAR or LINEAR NO FEEDBACK.
Motor driven actuators
Example: Typical examples are actuators from Heinzmann (STG 6, 10, 30, 2040.)
It is in principle a DC electromotor driving actuator lever. Since it is a motor, it has integrating characteristic – as
long as the current flows through the actuator, actuator’s lever moves. Direction of movement of the actuator
lever depends on polarity of the current. This type of actuator has always position feedback. For this actuator
choose option ActTypex: Wiring: BRIDGE. For Heinzmann actuators, Jumper P21 – supply of the position
feedback must be set to option 0-10V. For Woodward and GAC actuators this jumper must be set to position 0-
5V.
