The ServoRelay™allows a servo signal to control (toggle) the relays state making it ideal for any RC control application.

The ServoRelay simply plugs into a standard RC receiver just like a servo and you connect the load you wish to control via the on board terminals.

A small on board adjustable potentiometer lets you select the point at which the relay is activated. The ServoRelay does not require an additional servo channel!

The ServoRelay module is a simple to use, isolated two-position switch that can be turned on and off from a spare channel on your radio control receiver.

With both normally-open and normally-closed contacts and an adjustable switch threshold, this tiny product has unlimited applications, from controlling auxiliary lighting on an RC model to remotely operating cameras to take pictures from the air.

  • Small: 15x15x13mm
  • Adjustable Potentiometer lets you set the point where the relay switches.
  • LED positioned for easy viewing.
  • Learns transmitter characteristics for more reliable glitch free operation.

ServoRelay plugs into a standard hobby radio control receiver just like a normal servo. Simply connect the load that you want to toggle to the high quality screw terminals. Depending on the channel you use, you will then be able to control the load by moving the relevant stick or switch on your radio controlled transmitter. ServoRelay has an adjustable switching point which means the module can be set to switch when a transmitter stick reaches a particular position. This can be used on an existing occupied servo channel (with "Y" Adapter lead), for example, to activate turning lights on a model or emit a smoke trail when a plane is at full throttle.

ServoRelay includes a status LED which lights up when the relay is on, and vice versa. It also indicates if your radio link is too weak by flashing repeatedly.

The relay is a single pole double throw switch which means you have the option of inverting the behaviour by changing terminals. The contacts are rated to 1Amp switching current and work well with resistive loads like lights (inductive loads should be avoided).
