2rlp Posted July 19, 2012 Report Share Posted July 19, 2012 Hi, I have an amplifier which outputs 0 to 5 V depending on the sensed condition. However due to an oversight, I had ordered EX DI16 AI3 TO16 module. This module has 3 Analog inputs of 0 to 20 mA. The amplifier specs state that its output impedance is 100 Ohm, the input impedance of the analog input is 190 Ohms. So on connecting the output of the amplifier to the analog input, I get a value of around 19 mA (978) counts in MI corresponding to the analog input. Is scaling the counts such tha 978 corresponds to 1023, the only solution? Or can the input be made to receive 20 mA? Thanks Ron Quote Link to comment Share on other sites More sharing options...
