AVMASTER RELAY 14VOLT & AVMASTER RELAY 28VOLT

The AvMaster Relay is the first and only self contained, fail-safe, avionics master relay package to protect expensive radio gear at an affordable price. The AvMaster Relay is installed between the power bus and the protected radios. The avionics master switch then controls the AvMaster Relay only and not the radios directly. Not only does the AvMaster Relay protect the system from transient electrical spikes during normal operations, its four parallel relay controlled circuits allow for individual fusing that separate all radios from each other. The fail-safe design of AvMaster Relay eliminates the need for a backup avionics master switch. If the avionics master switch ever fails, the pilot won't even realize it after the flight is over and the avionics master doesn't shut down the radio stack. The radios will just be controlled individually until the problem is resolved.

THREE AXIS TRIM RELAY BOARD

These Trim Relay Boards allow control of an aircraft’s trim motors from the typical switches found in most stick grips. As the switches in the grips are too small to handle the motor loads and usually do not have the required number of poles, the ‘TRB’ offers a simple, elegant solution that is easy to wire and understand. The boards have a per axis rating of 10A at 12 volts, (24V units are also available).
