TJ-100  Interface Module

The TJ-100 interface module allows easy wiring of the TJ-100 engine to one or two cockpits.  Each function is routed through a simple, individual cable.  This avoids the complex problem of routing multiple signals to various locations throughout the aircraft by soldering multiple wires together.  Connectors are standard D-sub with size/gender to prevent incorrect hookup.   The enclosures are billet-machined aluminum with an EMI -blocking interlocking joint, and the circuitry maintains shield continuity.


1. TJ-100 (15P) – This connector accepts all signals from the TJ-100 15 pin connector to be routed through the interface module.


2. Data (15P) – This connector routes all signals from the TJ-100 to the CAN/SD unit for data storage.  This connector mirrors the TJ-100 connector (1) above.  These two connectors may be swapped.


3. Primary cockpit (15S) – This connector routes signals to the primary cockpit.  These include engine display, hard stop (emergency kill), and optional Run/Stop switch.  The optional Run/Stop switch is used in situations where the throttle unit cannot be reached by the pilot(s), and the throttle unit is actuated by remote levers or slides attached to the throttle lever.  In this case, the throttle unit lever always remains forward of the starting detent (run position), and starting/stopping the engine is accomplished by providing/removing power to the throttle unit.  If starting will be accomplished by means of the throttle lever, simply connect pins 3 & 11 together to bypass this feature.  (Display unit power is not provided through the interface module.)


4. Secondary cockpit (9S) – This connector routes engine display signals to the secondary cockpit.  This cockpit does not have emergency kill or Run/Stop switch functions.  This cable is omitted in single place aircraft.  (Display unit power is not provided through the interface module.)


5. Throttle (9P) – This connector routes signals from the throttle unit to the engine.  This connector does provide regulated 10V power from the TJ-100 to the throttle unit.  This power is switched through connector 3 if the optional Run/Stop switch is used.

Cables – We provide generic cable drawings for each of the five interface module connectors showing connectors, pins, wires (individual and shielded), and the wire colors we typically use.


Installation – We provide an outline and mounting drawing for installation.

Cost:  $300 plus shipping.  We try to keep a couple of these in stock.  If we happen to be out of them, lead time is normally about two weeks.


Note: The TJ-100 interface module was designed, and is manufactured by, Desert Aerospace, LLC.  It is not a PBS-provided component.
