The invention relates to a universal HART (Highway Addressable Remote Transducer) transmitting module and a work method. After carrying out sampling for a multichannel analog and digital transducer, a multichannel signal sampling module carries out filtration and amplification and sends signals into a microprocessor module. A constant voltage / constant current excitation module receives the control signal of the microprocessor module and supplies the transducer with excitation voltage or current. After the microprocessor module calculates, processes and converts sampled signals, a HART communication module modulates and demodulates HART signals and outputs the HART signals to a HART master station, and a current output module outputs 4-20mA loop current to an upper-layer control system. The universal HART transmitting module adopts a measurement, conversion and dynamic configuration output method for multichannel measurement signals, accomplishes measurement, conversion and output for multiple process measurement values of an industrial site, and forms a bidirectional digital communication channel with the upper-layer control system. Therefore, the upper-layer control system can dynamically configure, monitor and measure the multiple process measurement channels of the site in real time.
