REL-2 Servo Relay Deck
Installation Instructions
Secure the REL-2 Servo Relay Deck to the airframe or simply tie it onto a bundle of wires. Wire according to diagram
below. Do not install the REL-2 where it is exposed to excessive heat or vibration. The REL-2 is rated at 1 amp. Fuses
and circuit breakers are not included.
There are two relays inside the REL-2. These relays need 12-14 VDC applied to the red wire to operate reliably. (The
servo motor itself can operate at a lesser voltage.) A separate blue wire sends this variable voltage directly to the servo.
If you are not using our SPD-1 servo speed control, simply tie these red and blue power wires together.
NOTE: Test to determine if the servo(s) run in the direction that you desire. This direction can be changed by reversing
the two white wires that connect the servo to the relay deck.
CAUTION!! Be careful that the two white wires running to the servo do not touch ground or short together.
Do not power the relays with a battery charger.
