Analog sensors: AOUT2 0% = 20% (20% from 20mA = 4mA)
Analog sensors: AOUT2 100% = 100%
and jumper P6 adjusted to current option.
In case an actuator with an input 0-5V is used, the AOUT2 setpoints should be adjusted in the following way:
Analog sensors: AOUT2 0% = 0%
Analog sensors: AOUT2 100% = 50%
and jumper P6 adjusted to voltage option.
4.4.7 Interface to actuators
ECON-4 has one interface to actuator. The interface has a bipolar PWM output in bridge configuration and
position feedback input.
It is recommended to connect PWM output by a twisted cable and connect feedback input by a shielded cable.

Types of actuators supported by ECON-4
With current input 200mA
Example:
Typical example is Woodward UG-A.
It is electro-hydraulic actuator – in principle a small electromagnetic actuator with hydraulic booster. It has
proportional characteristic – the bigger is the current, the bigger is the angle of the actuator, the polarity of the
current is not important. Actuator is usually without electrical position feedback. For this actuator choose option
