Posted: Wed Dec 11, 2019 8:03 pm Post subject: Flap relay

Does anyone have experience with the Aircraft Extras relay board? I am considering two flap switches on my panel (Zenith STOL 750), one for pilot and one for instructor, which would require a relay deck to interface to the flap motor. The motor has a full-stall draw of 4A, so it is way beyond the 1A rating of the Ray Allen relay deck. The Aircraft Extras unit is rated at 10A so that should not be a problem, but I was wondering if they have a good track record for reliability, ease of installation, etc.

   Buy a couple of these:

  wire them like this:

  Inexpensive, works good, lasts a long time

That looks great, Bob. I guess I could use these for my trim system too, less $ than the RAC relay deck..

I see that the 12V version of the unit you linked to is out of stock - should I look for any 5-pin automotive relay with similar specs, or is there something special about this one?

I tweaked your wiring diagram for my 2-switch setup:

Pat does this allow for "ïnstructor" override?

   Yes . . . if BOTH switches are operated

   but in opposing directions . . . the motor

   simply stops.

   Check the corrected link for the intended

   wiring diagram.



   Nothing 'special' . . . any of the 12v, 5-pin

   devices will do nicely. Some are offered with

   a mating plug and wire harness which has some

   advantages but sorta complicates diode installation.



   But still doable.



   Going right to the relay pins with fast-on terminals

   lets you mount the diodes right at the relays . . .
