Use a single board, . . .
. . or stack them to 3 levels high.
Use as:
General purpose relays
or
Control stick relays (1 Axis,
2 Axis, or 3 Axis) control for flaps, elev. trim, etc.
These relay boards will allow you to use any inexpensive SPDT switch to
control your flap and elevator trim motors.
There are 2 relays per board. Each relay is a "Form C" relay (one
normally closed contact and one normally open contact).
Each relay board is 3" wide by 1-3/8" deep by 3/4" high. The standoffs for
the single boards measure 3/8" high. This makes the overall height 1-1/8".
What
makes our relay board different from the competition?
1.) Our relay boards include two (Single Pole, Double Throw)
"Form C" relays.
2.) The relay contacts are protected against inductive sparking generated
from relays switching inductive loads such as motors. This saves the relay
contacts and adds to the relay’s longevity.
3.) You can use multiple switches to drive one relay board. These can be
used for pilot, co-pilot, panel, etc. switches to control the same motor.
4.) You can connect a motor speed control or lower voltage source to these
relay boards. Using our relay board in this manner allows you to switch gears so
to speak, allowing the motor to be driven at different speeds. You may connect
several switches and relay boards to drive your motors at different speeds.
5.) This relay board allows you to multiplex ALL of your manual switches with
any automatic motor controller(s). For example, you may control one motor with
several switches (pilot, co-pilot, & inst. Panel) and an automatic flap
controller like the FPS-Plus.
6.) You can mount up to 3 relay boards in a neat stack to save on panel
space. All terminals are very user accessible.
7.) All switches mounted on your panel or in your control stick can be
simple, low current, (Single Pole, Double Throw, (ON Momentary)-OFF-(ON
Momentary), 3 position switches that you can purchase almost anywhere.
8 .) This relay board will control low current motors as well as motors up
to 10 Amps.
9.) Mounting hardware is included with our relay boards.
10.) Aircraft Extras, Inc. provides an easy connection diagram that you

Connection Diagram)
11.) Several customers have asked how to connect a flap motor that was NOT
clutch driven to our relay boards. In other words, they were using a flap
motor that requires limit switches to stop the motor travel at the ends.
We provided the following diagram for a bit of wiring help.

NOTE:
Make sure you click the proper item below for 12Vdc or 24Vdc operation.
Our 24V relays will work just fine on 28V aircraft systems.
