JT3051TH Diezoresistive HART Circuit Board replaced the original 4~20mA analog board. With the main body of Microcontrollers CPU, JT3051TH is capable to do logical operation and programming, combining analog and digital circuit in one machine, so it is able to output analog signal as well as carrry HART protocol signal on 4~20mA analog signal. Parameters configuration and compensation of transmitters can be done by buttons, HART communicator and HART configuration programs. JT3051TH provides constant current excitation way for sensors, supporting standard diffused silicon, piezoresistive ceramic, single crystal silicon and level sensors. It is suited for standard 3051 housing.
