    The Description of Display Annunciator

    LDG3000 Intelligent LED Pole Display Annunciator adopts microprocessor to carry on control operation. Insulation design and non-jumper technique can correct various non-linear import signal with high-accuracy. It can collaborate with various sense organ and display, call the police and transmit measure signal such as temperature, pressure, liquid, discharge, speed etc. The gauge possess some functions which are all-powerful signal input, break of conductor calling the police, outrange indication, self-correct and self-diagnose etc. String-cling serial communication input can communicate with various string serial input/output
