EM-M14 is an easy way to isolate current loop signals obtaining a good accuracy. No additional supply voltage is required. Voltage drop is minimal although the input voltage range is very wide. EM-M14 isolator is effectively protected against misconnections, over voltages and over currents. Output current can also be converted to a voltage signal with the inbuilt 100 ohm resistor. NOTE: As an additional feature the EM-M14 module can also be used to isolate loop powered transducers.
