RS08 Remote Switch Manual |
Section 1.0 Description
1.1Introduction
Information in this section consists of: purpose of equipment, features, specifications, and a listing of all models available to the date of publication.
1.2Purpose of Equipment
The RS08 is a bulkhead mounted remote switching unit. handle the switching requirements of two navigation NAV1\NAV2) sharing a common NAV system indicator.
It is specifically designed to systems (i.e. NAV/GPS,
Switching control for the RS08 comes from an external switch, and provision is made to force the return of the system to the VOR/ILS display, if an ILS station is selected by a connected nav system.
The RS08 provides switching for FLAG, TO-FROM, and DEVIATION lines, as well as providing annunciation output to show the display status of the common indicator.
1.3Features
Dry circuit to 2A contacts are provided for 6 poles, and 2 poles are furnished crosslinked to provide positive functional annunciator drive, with a built-in lamp dimming function (100 mA Max.) This provides the maximum possible safety margin for the pilot's mode indicator.
Glideslope/ILS interlock is provided for indicator return to ILS mode, where allowed by local Regulatory Authorities. Loss of power automatically returns the indicator to the primary NAV aid. The RS08 Remote Switch operates from +9 to 33 Vdc without change in interconnect.
All interconnect and relay contacts are gold plated. Relays are sealed, high vibration rated (50g shock), dry nitrogen filled units. Circuit boards are constructed of G10-FR (flame-retardant) material, with solder masks, reflowed tin plating, and environmental post-coating.
