RELAYS, HYBRID, ESTABLISHED RELIABILITY, GENERAL SPECIFICATION FOR

inactive
Organization: DLA
Publication Date: 22 October 1982
Status: inactive
Page Count: 37
scope:

This specification establishes the general requirements for relays that use a combination of solid state circuit input elements functioning with an electro-mechanical relay that performs the switching functions associated with control system applications (see 6.1). These relays are designed to operate in low and medium power switching circuits with contact ratings up to 10 amperes alternating current (ac) or direct current (dc). The failure rate level is established at a confidence level of 90 percent for qualification and 60 percent for maintenance of qualification based on 100,000 operations at 125°C under rated load conditions specified herein. Excludes time delay relays. (Caution: The use of any coil supply voltage less than the rated coil supply voltage will compromise the operation of the relay.)

The military part number shall consist of the letter "M", the basic number of the specification sheet, an assigned dash number (see 3.1), and a suffix letter designating failure rate level (see table I) as shown in the following example:

The failure rate level designation is shown in table I (see 4.5). TABLE I. Failure rate level designation.

intended Use:

Relays conforming to this specification are intended for use in electronic and communication equipment. Their principal areas of application are for aircraft, missiles, spacecraft and... View More
