The Ultimate TRB & Hub ! 25-Pin D-sub Connectors

The Ultimate TRB & Hub !  25-Pin D-sub Connectors

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.

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.

You can download the Manual here.

The Ultimate measures 2.5 x 3.8 inches and weights 4.25 ounces. Part number TRB-03FDDi.

    I ordered my relay board last weekend. Both of my infinity grips are now installed and wired. It made it easy. Pat even drew a diagram showing me how to incorporate my flaps-limit switch.
    Thanks for a great product!

    Pat,

    Just found your web site and am interested in your products for my Infinity Sticks now being installed. Question: I have the lever-lock switch to deactivate several of the C/P stick functions when I have a Young eagle (or Old Eagle) in the right seat. Can that switch be incoporated into your system ?

    Thanks

      Thanks, Larry. Yes, absolutely.

    Where is the wiring diagram, can't do anything without it!

      Sam, should have been in your package, however I just emailed you a copy. Thanks!

    Hey Pat, I have the Ultimate 3 channel. I'm a electronic dummy. Do you have any schematics on how to incorporate a "lockout" or "Grandson" switch so that I can lock out the rear stick if need be?

    Cheers,

    Don

    Hi Don, it's just a matter of gathering all of your "ground" wires coming from the copilot stick (you could use a small terminal strip), ganging them together into one wire, then using a SPDT switch to either "arm" the ground wires or "disarm" the ground wires, depending on the position of the switch, and connecting the other side of the switch to one of the GND terminals on the Trim Relay Board. See your email, I sent you a schematic illustrating how to do this and included a part number for a suitable switch. Cheers. Pat

    I have been flying with Pat's relay board for 3 years. Great!

    I am building an RV-9A. I am "roughing-in" the airplanes electrical system now, running wires all over the place.. I am installing Pitch and roll autopilot (GSA28 servo's by Garmin), along with a G305 Autopilot. I also have Ray Allen Pitch and Roll servos. I would like to be able to control the whole thing from my two sticks.

    It looks like the Ultimate TRB & Hub will do the job.

    Where is the UTH mounted?

    Can you forward me a wiring diagram that integrates your device in with my devices.

    Please verify that your UTH will do the job, and I'll order one.

    Thanks,

    Steven

      Steven, I replied to you via your email address and attached a schematic for you. Yes, the UTRB will be perfect for you, I have the same exact setup as you on my RV-6, works beautifully. Let me know if you have any questions.

    The schematic is provided with the kit.  If you would like a schematic, please email us directly.  Thanks!
