SR34-1 Module
(DAI Part# 306110-00)
For installations where price is the major consideration, SANDIA aerospace offers three cost effective, yet reliable switching solutions. The SR24, SR34 and SR64 use sealed, bifurcated relays that provide a high degree of reliability and self clean each time the contacts are exercised. The gold contacts have a life expectancy of 500 thousand operations at 2A/30VDC or 2 million operations at 1A/30VDC. With the ability to carry 2 amps of current, these switching modules are suitable for a wide variety of avionics applications.

The SR34 uses three, four-pole sealed relays to provide a total of 12 lines of signal level switching.
