(Doug McNutt) ________________________________ Message 1 _____________________________________ Time: 02:32:40 PM PST US From: Doug McNutt Subject: Avionics-List: PMA'd relays? I'm looking for a source of approved relays for a project I'm working on that will need a field approval. The airplane is a Cessna 207 with a 12 volt system and it's getting a 200 amp alternator and a 60 Hz 2.5 kW 60 Hz inverter. What I need are a DPDT 14 volt relay and a DPDT 120 VAC relay that I can use to get the switching logic I need to switch between ground and flight operations. Actually I have space-qualified relays from Potter & Brumfield and Filtors Inc. but they are no longer made and never had any kind of FAA certification - only NASA and perhaps the USAF. They'll work fine but I can't document them for the feds. The transmit/receive relay from an old Narco COM11 is one option but they come from the likes of Digi-Key and don't carry a PMA sticker unless you're Narco or King. Any ideas? -- --> Evolution made it possible for mankind to invent religion. <-- ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message avionics-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Avionics-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/avionics-list Browse Digests http://www.matronics.com/digest/avionics-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
