I need a triggerable high speed analog input card. So I can do power waveform feature extraction and fast real time control.
Like a DSP more or less.
We are actually thinking about something like this. We are building very high speed analog for a custom application, and have been considering how we could use the hardware as standard product. First thought is to allow selection(s) of a) sample rate, b) bit depth, and c) data stability. Basically you pick any two, and we'll tell you what the third is. To support speeds faster than the PLC scan, we'd make the module capable of interrupting the PLC on new samples. So for apps like yours, you'd pick the sample rate you need and the minimum number of bits that would do the job, and we'll tell you how sloppy your samples will be. Haven't yet worked out how it would get enabled (for a capture cycle), but that shouldn't be a too difficult.
Not applicable to your app, but the opposite end would be supported too. You need 32 super stable bits? Cool...might take 10 seconds per sample, but it could do it. That side isn't too bad now, since you can oversample existing analog, but having the module manage it is nice.
We were a little concerned that a module like this might be a solution in search of a problem, so it's good to hear a customer request it.
