• Two Mil-Bus 1553 isolation channels

• Two buffered outputs per channel

• Compact and rugged construction

• Stackable for multi-channel configurations

• Flight testing

• Mission data monitoring

• Avionics test rigs

gle/BIM-102 is a rugged and compact unit designed to isolate, split and buffer a dual redundant Mil-Bus 1553, in order to connect two redundant buses monitor on a single redundant external bus coupler.  

All Mil-Bus 1553 I/O are done via Trompeter Twinaxial connectors, while the power supply is pass-through by means of D-Sub connectors, in order to stack multiple units with only one power supply connection.   

Each I/O connection has its own Mil-Bus 1553 isolation transformer.

Each input requires a Mil-Bus 1553 external coupler.

gle/BIM-102 units have been used to support data acquisition tasks within the flight testing and certifications activities of military aircrafts, as for example EFA Typhoon.
