Help indentifying component.

[TomW]

Awhile back I salvaged some industrial equipment from an estate sale I helped my stepdaughter with.

It yielded some very interesting components. I have figured out most of them but these 3 devices that I believe to be some type of segmented display. It would be very good if I could use these as indicators for voltage [or something] in my system.

Here is a link to the [quite large] detailed photo I took this morning to see if anyone here has a clue where I can get a data sheet or other info for it. The photo is of all 3 with all markings shown as well as connectors and face.

Any help appreciated.

This may be Nixie tube display.

If you can shine a light into display, you may see filament wires in the dhape of numbers one filament  behind the other. They are shaped in numbers from 0-9. The illuminate with low voltage. Different ones operated with different voltages.

Approx 5 volts to 12 volts

I clearly see 7-segment LED displays

I did a search on the Chip Number RU-NL16 and found this data sheet PDF

It might be really helpful

especially if you can read Japanese

Woof;

Well, luckily, schematics are relatively language neutral.

Lots more than I managed to get google to spit out.

Thanks.

If I had to guess, I would say the display was a type of VFD display. I don't think it would be a Nixie. If it is a VFD, it requires a bit less voltage than a nixie. I don't know if that helps you but you might try looking for VFD displays and a general voltage range...

Hi

Nixis are generaly round they are a vacuum tube and high voltage, how many conections on the back are there, if its 8 to 10 they could be 7 plus decimals sement or LED displays. 7 Segment easy to use but lots of wires, drive them with a to BCD 7 segment converter. If they are BCD displays, then you could drive them with binary to BCD converter.

Probably cheaper to use a dedicated LCD meter module, and less power.

Think yourself lucky they are not decatron tubes, but you could watch the dots go round.

Well, I learned something today too.

I'd never seen a 7-segment nixie tube and while I do have some high-voltage 7-segment displays, this was an interesting find: Rodan 7-segment Nixie tubes

Here's a Beckman two-digit 7-seg: Front and Back

Looks like the displays out of a gas station pump... Never seen one out before..
