Product Update: We have now modified our Ultimate TRB to include 3 discrete voltage inputs: one each for flaps, pitch trim and roll trim. Now each circuit can be individually protected with a fuse or circuit breaker. It also allows for a speed controller(s) if desired (for the pitch trim, for example). We have also added spike suppressor diodes for longer life of the relays and the actuating switches. New: we just upgraded our manufacturing process to include solder masking of the PCB!
Our Ultimate Trim Relay Board. The Ultimate uses a plug-and-play design approach which allows you to organize and centralize all of the inputs from both grips. The Ultimate also serves as a wiring hub and gateway from your grips to your trim system and other functions. The Ultimate will facilitate your grip wiring and function as a convenient access for maintenance and troubleshooting.
The Ultimate uses two 25-pin D-sub connectors which allows you to wire any two grips in parallel using all of the functions on both grips--including flaps or speedbrakes. It also is a ground bus consisting of 16 ground pins. There are enough pins on each connector for all the pilot and copilot functions plus all the grounds.
Installation Manual and a Schematic are included along with all the required mounting hardware and attaching D-sub connectors. Note: machined pins and sockets not supplied. If you need pins and sockets, they are available on the Products page. You'll probably need a pack of 25 sockets and one of 25 pins.
