Measuring Voltage in Extremly Noisy Environment

[roydm]

Hi, I have an application where I need to measure battery Voltage in a noisy (RFI switching regulator) environment.
I need a significant number of transducers 0 - 150 VDC sending data to an AB PLC.
It's pretty hard to shield the transducers since they need to be connected to the same cables that are radiating the noise.

I was hoping to find network transducers similar to the metering I have seen in large switchboards.
I thought fiber optics would be a good method of isolating the noise from the PLC.

If anyone can give me some pointers I would appreciate it.

Thanks
Roy
