Page 9: Introduction
4–20mA Loop The DewPro MMY31 Transmitter is powered by a voltage supply of 12 to 28 VDC. At the nominal 24 VDC supply, the maximum loop resistance is 600 ohms. The signal is represented by the 4–20 mA loop current and is directly proportional to the dewpoint temperature range in °C or °F. - Page 10 Chapter 1.
