[N4NV]

I am trying to get information on an encoder. It is a Heidenhain ERO.
The encoder is marked:
ERO 120 500 F10
iDNr 220 155 10 sNr 1551729.

I looked at Heidenhein's web site with no luck. I have emailed them but they will not be open until Monday and I would like to work on them before then.

I am trying to find out the voltage, count, and current draw.

Thanks

Vince
