Existing reviews of 3 Phase AC Voltage Transducer 10V to 500V, Output 0-5V/4-20mA/0-20mA
I want to buy your voltage sensor
I have come up with your product below:
Though, I have 2 questions:
1) I see there are several inputs for Voltage from 0V – 1000V. My first question is how can I select a range of fe150V?
In such case, what will the accuracy at low voltages fe 4V (I need accuracy of 2 decimals)?
Is there an option to switch between 2 ranges in one single sensor?
2) If I adjust the output range to 0-10V (this is my acceptable PLC input), what will be the output in case of reverse polarity connection? I really want to avoid a negative signal on my PLC input.
