Page 7: Section 1 General Description
Section 1 General Description 1.1 Introduction This manual describes the installation of the SANDIA aerospace MARC70 line of interface mod- ules. It is intended for use by FAA certified repair stations to install the MARC70 modules. It includes both the mechanical and electrical installation information for all MARC70 components, including the individual modules and enclosures. Where applicable, alignment and checkout proce- dures are included. -
Page 8: Sru 5
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. -

Page 13: Section 2 Installation
Introduction The MARC70 family of enclosures and interface modules has been designed to simplify and standardize installation of avionics systems. SANDIA aerospace supplies each mounting enclosure and interface module separately. The installer can mix and match the modules in the enclosures to meet specific requirements. Except for the SR 34, SR 54 and SR 64, each of the module’s connectors is keyed to prevent inadvertently attaching the wrong connector. -

Interconnect Wiring 3.3.1 SA 3 & SA 3L Regulator/ Dimming Modules The SA 3 & 3L Regulator/ Dimming Modules provide a source of power to drive up to .5 amps of continuous current for aircraft annunciators. The SA 3 & 3L will provide 1 amp short term for testing of annunciators. -
Page 18: Sa 24 Diode Isolation/Test Module
3.3.4 SA 24 Diode Isolation/Test Module The SA 24 provides 23 lines of diode isolation. The SA 24 also provides a test input for testing annunciators. The test input can be either a high or a low. Pin 48 on the SA 24 is the keying pin and has been removed at the factory. -
Page 19: Sr 263 12 Pole Switching Module
3.3.8 SR 263 12 Pole Switching Module The SR 263 provides 12 poles of switching through two MIL Qualified, hermetically sealed, and nitrogen filled relays. The relays contacts are gold plated hardened silver alloy with a 2 amp resistive load capacity at 28Vdc. Coil power is 2.6 watts max. at 25 degrees C. Each relay can be activated independently by supplying the switching logic to their coil through pins 38 & 40 for K1 and 43 & 44 for K2. Or they can be switched as a pair by sup- plying the switching logic to pins 39 &... -
