Our relay contacts
are protected against inductive sparking generated from relays switching
inductive loads such as motors and solenoids. Our relay coils are also
protected. This prohibits the relays from early failure. This also protects the
switch contacts that drive the relay coils from failure. NO relay boards have
been returned to us for failure in over 16 years!

Axis, 2 Axis or 3 Axis control.

contains two, SPDT relays (Form C). Each relay has 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".
Our relay coils
are actuated by pulling them down to common or ground. If you desire to operate
them pulled up to + bus voltage, we can make one for you, no extra charge, just
Features - Advantages
Our relay boards
will allow you to use any inexpensive SPDT switch or stick grip switches to
control your flap and elevator trim motors.
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.
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.
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 switch, etc.) and an automatic flap controller
like our FPS-Plus.

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.
