AE RELAY BOARD

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 1/4" high. These make the overall height 1".

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 relays 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.

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.
