Isolated Analog Voltage Input Modules For Testing

[danner123]

Hi everyone, I need to measure analog voltages and want to isolate them from my measurement system to prevent any potential damage. The analog voltages being measured are +/-10V max.

Can anyone suggest any good Isolated Analog Voltage Input Modules? I'd like to find a module that supports at least 4 voltage inputs for isolation. I will then pass them to my measurement equipment.

Thanks!

Hi,

You should specify:
* frequency range of the measured signal
* is the signal DC free?
* is a true replica of the waveform important... how much distortion is allowed
* is there a restriction on delay time between true and isolated signal
* do you need isolation between the 4 channels
* how much isolation voltage do you need
* do you expect a pure analog solution or a mixed solution

I believe that Texas Instruments also has some offerings, but have not checked lately.
