Overview

MARC70 Interface Modules provide the avionics installer with simple, PMA Approved installation solutions. SANDIA Aerospace Modules are ideal where reliability is a must such as in Navigation System, GPWS, TAWS and RVSM installations. Each module can be installed in either a SRU-1, SRU-5 or SRU-10 enclosure, maximizing installation flexibility. These interface modules can be combined together in a single enclosure to provide a complete installation solution.

The SRU 1 is a single card enclosure which accepts any MARC70 interface module. The SRU 1 is ideally suited for installations where only one MARC70 card is required or where there is limited real estate for mounting the larger enclosures. The SRU 1 can be mounted in any axis and either inside or outside the pressure vessel.

The SRU 5 is a multi-card enclosure that accepts up to five MARC70 interface modules. The SRU 5 can be mounted either inside or outside the pressure vessel. When less than five interface modules are used with the SRU 5, cover plates are placed over the unused card slots. If additional cards are required at a later date, the cover plates can be removed and the appropriate interface card installed. When installing the SRU 5 ample room should be allowed for both connector clearance and for inserting and removing the interface modules. The SRU 5 as well as the interface modules can be mounted in any axis.

The SRU 10 is multi-card enclosure that accepts up to ten MARC70 interface modules. It is ideally suited for installations that will require more than five interface modules. As with the SRU 5, unused slots are covered with cover plates included in the installation kit. These extra slots can be used on future installations, eliminating the need for additional mechanical engineering and approval. The SRU 10 can be installed either inside or outside the aircraft’s pressure vessel. For installation flexibility, the SRU 10 and the installed interface modules can be mounted in any axis. Ample room should be allowed for both the connector and for inserting and removing the interface modules.

The conditions and tests performed for FAA-PMA approval of these articles are minimum performance standards. It is the responsibility of the installing agency to determine that the aircraft operating conditions are within these FAA-PMA parameters.
