Stand-alone encoder read

Has anybody ever heard of the following :

A stand-alone module that reads encoder pulse trains, calculates accel, decel, top speed and distance travelled, and then outputs this data serially, with a reset input to clear it for the next sample?

Thanks!

Sounds like a job for an AD DL-06 .

The dc input model comes with a 5 hz counter, or you can buy a option card with a high speed counter. Serial com on port 2. Lots of math functions. Take a look.

Yes,

It ia called a motion controller.

Peter just after I posted I reliized that...... Thanks to you.

Digging into it

Thanks guys,

The AD DL6 is a full-on PLC, and I've already got one o'those. The problem is, my HSC doesn't go anywhere near fast enough, so I'm looking for a work-around.

Peter:

I'd considered that also, but motion controllers are frippin' expensive, especially when I don't need "control", just a counter with a little built-in IQ.

There are some interesting pop-ups doing a search on Google for this using Data Acquisition as a search term. Among them, AD offers a Terminator IO unit that is right up my alley, except it doesn't support the Modbus protocol yet.

Still looking.

Thanks again!

I think he is looking for something along these lines:

I know absolute encoders can use different serial/bus connections but not sure about incremental: http://www.patchn.com/absolutencoder.html

Ron's a genius

Ron, you're a genius. That's exactly what I'm looking for.

Not alot of info at the website. Do you have any experience with this module, like how many channels it has?

Thanks!

Tim,

Did you look at the optional high speed counter module for the DL06?

You didnt mention spicifics on the encoder, or the application, but the H0-CTRO will count up t a 100 khz pulse rate, which is pretty fast.

Additionally I'm pretty sure the DL-06 can do Modbus also.

I worked on a system that had one of these on it but never had to actually work with the unit, just got the info in case.

I am not sure if it has multiple inputs or not, if it seems to fit the app then I would call them.
