Electric damper actuators
Electric damper actuators
(OP)
I have a project where I've been asked to control a electric damper actuator, specifically
http://www.valvesolutions.com/pdf/gca%202p.pdf
using a 0-10VDC signal for positioning. I've been looking for some sort of document that discusses the 0-10V control but haven't been successful yet.
Questions really are...0-10V equates to a position? This is only the control, separate from the actuator voltage, or is it the same? The cut sheet really doesnt lend itself to explaining how to use the device.
If this is the wrong forum, let me know...wasnt sure this or the PLC forum.

Look at the device sending the 0-10VDC signal. Reprogram it for on-off control and then use an interposing relay to switch the power to the actuator. You will still have on-off control of the actuator. If you need to modulate the damper you must change the actuator.

This damper still requires power as well as a 0-10VDC, 2-10 VDC or 4-20 mA DC control signal. (a 500 Ohm resistor across the control terminals will convert 4-20 mA DC to 2-10 VDC).
BUT BEWARE! Fire codes or environmental concerns may require a spring return damper that will automatically close when power is lost. You may have to keep the spring return damper and forget modulating the position.
