A 20 Pole switching card for use with NAV systems that share the HSI/CDI’s OBS function; PMA’d NSN 5990-01-541-7597
The SANDIA Aerospace MARC Series of remote accessory cards provide the
installer with a wide variety of interface circuits needed to integrate
today's avionics systems.
Each MARC35 comes housed in a single card enclosure.
The MD41-24P is a remote mounted transfer relay
unit specifically designed for switching a CDI or
HSI Indicator between two aircraft radio navigation
systems. The remote switching unit is designed
for use with GPS systems where the user desires to
share a common CDI or HSI between an existing
NAV system and a GPS system. The 24 pole unit
features 8 relays consisting of 3 poles per relay. Each
relay can be activated individually by either voltage
or ground keying or as a group by ground keying.
Other design features include complete interlocking
of all transfer relays utilizing one pole per relay for
failure monitoring. A special ILS override that will
automatically force the MD41024P to switch to
NAV mode when the NAV (VOR) receiver is tuned
to an ILS frequency. Also, an adjustable dimming
regulator is included to provide dimmed voltage
to an external annunciation (750 ma max). All
transfer relays have gold plated contacts and are
nitrogen filled for high reliability. More Info...
The 6543210 lighted indicator uses four bulbs, providing a redundant
safety feature. Custom legends and different color choices make these
indicators useful in many diverse applications. Legend colors are
red & amber. Other colors are available. More Info...

The SANDIA Aerospace
MARC Series of remote accessory cards provide the installer with a wide
variety of interface circuits needed to integrate today's avionics systems.
The MARC70 units can be housed in an SRU 1 single enclosure or can be
installed in either the SRU 5 or SRU 10 multi-card enclosures.
The SRU 5 will hold up to 5 interface modules while the SRU 10 can hold
up to 10 modules.
The RS08/12/16/24 family of remote
switches allow large numbers of data or audio lines to be transferred
with a single ground logic level. 14 VDC or 28 VDC operation is
supported and the RS08 series features automatic ILS reversion logic.
The RS08/12/24 series are Transport Canada Type Approved for
installation in IFR and restricted aircraft. More Info...
