Red Lion Controls ITMA2003 Thermocouple Analog Output Current Converter

The ITMA2003 Intelligent Thermocouple Module with Analog Output from Red Lion Controls converts a thermocouple (J, K, T, or E) or millivolt input into a 4 to 20 mA current output, providing a linear representation of temperature or millivolt signal that can drive indicators, chart recorders, controllers, or other instrumentation. In the loop-powered configuration, the same two wires supply power and carry the 4–20 mA output, typically drawing less than 4 mA, with a supply range of 12 to 42 VDC. The unit mounts on DIN rails (T and G styles) and is packaged in a compact 22.5 mm-wide module, configured via a 10-position DIP switch for range and field calibration, with 2‑way electrical isolation between input, output, and power. It supports thermocouple inputs and break-detection, making it suitable for reliable process temperature monitoring and control in industrial environments. ITMA2003 denotes the loop-powered variant of Red Lion’s intelligent thermocouple family, designed to translate primary sensor signals into standard 4–20 mA current loops for compatible process equipment.
