pulse generator from analog output
 
Good Morning, Customer has given me a PAX2D Red Lion timer to read and display the speed of a motor.

The drive only has analog outputs, but the PAX2D is built for high speed pulses. I am just curious if there is a device out there that you could recommend that would take a 0-10V output and covert it into 0-50khz pulses. For example, at 5 volts it would put out 25khz and at 10 volts it would do 50khz. These numbers are for illustration and I don't those exact specs but that is to prove the concept.

If this is not practical, i do have some other options but this would be my first choice. I can buy a PAX2A, but the customer wants the PAX2D because that is what they use all over the plant.

Any thoughts or suggestions?

See if this will do it. I didn’t read all the specs
Or they may have something else

Yes, that would do the trick. It has a lot more features than what I need.

Do you know if they distribute over here? Have any experience with this brand?

Here's another option if you don't really need 50 KHz. The range is only 0 - 10 volts to 0 - 5kHz.

In the past.. I used their resolver interface
I spoke to my local distributor and gave them the part number
they ordered it for me

Phoenix should also suit, but 0-10V is 0-10kHz or much faster:

Thanks for your suggestions. They are helpful.
