JRoss Posted March 17, 2008 Report Posted March 17, 2008 I need a device that will convert an analog input signal (0-10V or 4-20mA) to a TTL pulse-train for a speed following operation. Has anybody run across something like that? I know I can use a PLC, but the end-user doesn't want a PLC at this location. Thanks.
tragically1969 Posted March 17, 2008 Report Posted March 17, 2008 Something like this ? (sorry its UK based) http://uk.rs-online.com/web/search/searchB...t&R=3384165
JRoss Posted March 17, 2008 Author Report Posted March 17, 2008 Excellent, that put me on the right path. Red Lion here in the states makes something like that: Signal Convertor Thanks again.

entertron Posted March 19, 2008 Report Posted March 19, 2008 (edited) Jeremy, How about something that doesn't look like a PLC? We may have something for you. How fast does your pulse train need to be? You may also want to look at www.calex.com Specifically - http://www.calex.com/Scdinrail8500.html Edited March 19, 2008 by entertron
