MTL3072 TEMPERATURE CONVERTER 3-wire RTD input.

The MTL3072 accepts a signal from a 3-wire resistance temperature detector (RTD) in the hazardous area, and converts it to a 4/20mA loop current in the safe area proportional to resistance (but not temperature). Calibration is carried out by the user via controls located in the top and the side of the unit. Input zero and span are selected by switches (coarse adjustment) and potentiometers (fine adjustment)
