Hello Gentlemen,
Just signed onto the aeroelectric list group. Hello! I am in the initial
stages of working on my instrument panel and breaker panel and have come
upon my first technical challenge, as well as many more to come I'm sure.
Please excuse my lack of knowledge and experience with electrons -- and a
quick thank you to Bob and all contributors to the fantastic AeroElectric
book and community --
I would like to actuate my flap system (building a Radial Rocket, Nashville,
TN) via some type of hat switch. It looks like Ray Allen provides something
(part number ROS-4) that would do the trick.
They also provide a relay board that would be able to handle the STSP to
DTDP conversion? Also have a voltage issue, as my system is 28V.
The flap motor is rated at 24V to possibly as much as 8 amps which knocks
the Ray Allen relay board out.
What I "think" I need is one relay board per flap action (up and down) that
can handle an 8amp draw from the motor, the small 11 mA ground signal from
the 4-Way hat switch and the 28V system. Is this correct?
I have no background in this but plenty of time to learn. Just looking for
some experienced hands here that can perhaps provide a schematic for the
following devices (again, devices that I "think" I need to make the
following work safely):
Ray Allen ROS-4 -- Two 4-way hat switches -- one per hand grip:
throttle: rudder trim on one axis, flaps on another
flight stick: aileron on one axis, elevator on other
Ray Allen REG-1 -- 12V Voltage Regulator (2, one per hat switch?)
Ray Allen REL-2 -- Relay board (3, one for aileron trim servo, one for
elevator servo, and one for rudder servo)
Ray Allen POS-12 -- flap position sensor for max 1.2 inches of travel
One, unknown Relay Board that will handle the above flap system. ??
Flap Motor: 24VDC, 3A No load, 8A up to 500 lbs, Motion Systems Corp model
#85151, part number 73485, Motor # PE2433R
Quite a lengthy hello to the group I know so thank you for any attention or
advice you can provide.
Andy
