Model ITMA Intelligent Thermocouple Module
Brand: Red Lion ControlsThe ITMA accepts a thermocouple or millivolt input and converts it into a 4 to 20 mA current output.
The 4 to 20 mA output is linearly proportional to the temperature or the millivolt input. This output is ideal for interfacing to indicators, chart recorders, controllers, or other instrumentation equipment.
The ITMA is loop-powered which means that the same two wires are carrying both the power and the output signal.
The unit controls the output current draw from 4 to 20 mA in direct proportion to the input change while consuming less than 4 mA for power.
The conversion to a current output signal makes the ITMA less susceptible to noise interference and allows accurate transmission over long distances.
The 2-way isolation allows the use of grounded thermocouples which can provide additional noise reduction benefits.
