Title: Encoder question
Post by: marky_mark on June 18, 2003, 12:28:17 PM

I plan on using an optical encoder which has TTL outputs. I would like to connect it directly to the the HSC input. Any problems with this or should I buffer it with a darlington array as shown in the inst manual?

Thanks.

If you can find an optical encoder that can output 24V NPN then you can connect directly to the HSC inputs. If your encoder is 5V only then you will need the darlington array to act as the interface between them.
