Orr Posted March 29, 2017 Report Share Posted March 29, 2017 Hi there, I have V700 with V200-18-E46B snap, I`m trying to figure out the connection to the analog input from 4-20ma sensor, The data of the v200 state that the maximum V in the analog input is 15, the sensor receives its V from the controller 24v, The output voltage from the sensor is 23. Volts .. Therefor I would assume there will be problem if I connect it to the input of the analog in (based on the maximum V in of the snap in 15v) Am i missing something here? do I need to provide lower voltage to the sensor? add something after the sensor to lower the volts? Help please. Thank you Quote Link to comment Share on other sites More sharing options...
AlexUT Posted March 29, 2017 Report Share Posted March 29, 2017 Hi Orr, It seems that you measure voltage at current output with open circuit. V200-18-E46B internal resistance for inputs AN0-AN2 (10-bit) is 500 oHm , and voltage limit is 15 V. For AN3-AN8 (12-14-bit) internal resistance is 37 oHm, and voltage limit is 1.1 V. B.R.
