We have field flow transmitter with power supply from the external source and is connected motor controller which is receiving the 4mA to 20mA current and is also powered from its controller. What type of barrier to be used in-between so as passive current to motor controller is sent?

 

Signal Isolator required here, P&F KFD2-CD-eX1.32. This will require A 24VDC POWER SUPPLY. or P&F KFD0-CC-1 for similar with no 24v dc supply required.
