Sandia AIS 20 Pole Relay Switching Unit | AIS 200B-35
Sandia's AIS 200B-35 is a 20-pole, signal level, switching unit designed for use with NAV systems that share the aircraft's HSI/CDIs OBS functions.
Internal fail-safe switching circuitry ensures that ILS steering is always displayed on the indicator should power be lost to the system or if an ILS frequency is selected in the NAV receiver. Annunciator outputs advise the pilot which system is being displayed on his HSI/CDI. As with our whole AIS family of switching units, the AIS200A-35 uses gold-plated dry contacts that are sealed in nitrogen-filled cases.
The rugged construction of the AIS200A-35 , makes them ideal switching units for both fixed wing and helicopter operations.
The AIS200A-35 is a multi-purpose switching unit. The twenty poles of switching allow all the resolver lines and the steering lines to be switched simultaneously.
