    I'm looking for data on an old 4PDT open frame relay. It should be about a 200volt dc relay, aprox 10K coil resistance and about 20 mills coil current. The part # is MH-3665. It was made in the '60's.

    TKS, Walt.

    What are you trying to do with it? If you can send your specs and a pix I might be able to ID it.

    Walt -

    Sounds like an old P&B 1960s catalog would meet the requirement. Where is the old Burnsee & Applebee (KC) when you need them :)

    Walt,
    I have a P&B Technical Data Book, It has one page on the MH series relays.
    I don't have a scanner, but the page is not very specific other than it says TELEPHONE-TYPE DC SMALL 5 AMP RELAY, maximum coil resistance of 22,000 ohms. They recommend R10 series as replacements. The picture shows open frame construction, but sealed enclosures available.

    I get the impression there were many versions available. Hope this helps.
