SM15 Rev. 4.00 RS12/RS24 Remote Switch Manual

Section 1.0 Description

1.1 Introduction

This manual contains information on the RS12/RS24 Remote Switch. Information in this
section consists of purpose of equipment, features and specifications and a listing of all
models available to date of publication.

1.2 Purpose of Equipment

The RS12/RS24 are compact, high density, bulkhead mounted remote switching units
designed to handle the switching requirements of navaid, audio, or other interface
applications.

The RS12 remote switch is a unique interface device that allows large numbers of data
or audio lines to be transferred with a single logic level control line. The RS24 consists
of two completely independent RS12 units packaged in one enclosure.

1.3 Features

The RS12 provides switching for 12 poles of information, organized as three 4PDT
relays, each with an individual key line. Each relay can be used independently, or can
be picked as one group of three relays (12 contact sets) by applying the required logic
level to the respective ALL KEY line.

The RS24 provides switching for 24 poles of information, organized as six 4PDT relays,
each with an individual key line. Each relay can be used independently, can be picked
as two groups of three relays (12 contact sets), or can be picked as one group of six
relays by applying the required logic level to the respective ALL KEY line(s).

These relays can be used for applications from dry circuit to 0.5 A switching, but are
limited to a maximum of 30 Vdc. They can be operated from +10 to +33 Vdc without
changing the 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
and reflowed tin plating; they are environmentally protected with conformal coating.
