Output signal corresponds to actuator requested position. The limits are fully scaleable in range 0-10V
(0-20mA).
E.g an actuator with input 4-20mA is used, the AOUT2 range setpoints should be adjusted in the
following way:
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.
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.
ECON-4 currently supports following types of actuators:
a) With current input 200mA – 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 ActType: Wiring: LINEAR NO FEEDBACK
