The DBR 5000 series developed by Compupower are designed for switching LRUs or RTs from one Bus or Stub to another or reconfigure a Bus. These switchers are Double Pole Double Throw (DPDT) relay devices, which act as ON-OFF Bus switchers to disconnect individual RTs or entire Bus segment from a Bus Network eliminating the task of manually disconnecting cables. Reconfiguring of a Bus is accomplished by applying 28VDC to the relay devices using D-subminiature connector. The Bus switching relays are energized just prior to separation by the aircraft or launcher controller. A problem that occurs in separable stages in launch vehicles is an open Bus or Stub at the time of separation. One solution to this problem is use of Data Bus Relay Devices. The idea is reconfigure the critical Bus(s) into valid Bus configurations by physically disconnecting from the exposed open leads and switching in a proper termination. Applications: Switching between two Buses. Switching an RT ON or OFF from a Coupler Stub. Segmenting a Bus between a controller and two RTs allowing either terminal to be addressed by the controller. Benefits: Ideal for test and simulation No cable changing Easy to use
The main feature of this Tester is that, these tests can be performed from the LRURT ends of the Stub cables because, access to the Couplers and Main Bus itself may be difficult.Easy to use hand held battery operated equipment
These Couplers are available with and without internal terminations and are for use in applications where mounting can be accomplished by wiring the Coupler into the harness. Qualified and type approved for flight and space applications Low cost Highly reliable
