Time Delay Relay Tubes

cadman · 17th December 2002, 02:57 AM

Just wondering, I've got an 115N060 relay tube here that I'd like to play with. The only info I've found is that it's a 60 second delay. From trial and error I figured the pinout but have no idea how to fire it up. Is this electromagnetic? Heated bimetallic strip? Any idea what voltage it would take to get these relays going or what kind of current this one can handle? 24DC does nothing. The prospect of a relay in a tube intrigues me though

TIA!

Hi,

You must have overlooked it...

Quote:

115N060

Now read again : ONE ONE FIVE=115V 60S

Nothing as easy as tubes.

BTW,that is an Amperite ignitron you're holding in your hands.

The tubeman,

Thanks tubeman! I couldn't see the forest from the trees

Any idea what the contacts are typically rated at?

And the NO = Normally Open contacts.....

and if there is a T at the end it means its in a mini 7 pin tube envelope and its 8 pin octal without a T at the end....

115NO60

normally open perhaps?

edit: ah damn, dave beat me

For the 8 Pin Octal version:
Heater -pins 2 & 3
Contacts - pins 5 & 7

Curiously, neither of the Amperite spec sheets I have list the contact current or max voltage etc.

Hi,

Good to see some of us still carry some databooks.

I don't have my Amperite books around anymore but from experience they can carry more current than you'd expect.

Assuming the US runs at 110VAc you can expect these tubes to withstand a whopping 10 Amps at least.

If any of us can't find precise data,Amperite themselves still can.

Cheers,

Found the specs:
Contact Information:
Arrangement: 1 form A (SPST - Normally open) - Delay on Make
1 form B (SPST - Normally closed) - Delay on Break
Contact Material: Silver - Cadmium Oxide
Rating (Resistive): 3A @ 115V AC
Expected Life @ 25°C: 500,000 operations minimum at rated loads
