  • C Series Universal Analog Input Module

Issue Details

I have an analog input module with multiple different voltage measurement levels and it's unclear to me what the specified safe input voltage of my device is.   

Solution

To find the safe input voltage for a device you need to look at the Channel to Earth Isolation value in the datasheet
 

Additional Information

Channel to Earth Isolation should not be confused with Maximum Measurement voltage which is the highest voltage value the device can detect.
