Data Acquisition
establish monitoring programs. In addition to the above functions, the RTU-140 also supports RTU Center related monitoring functions. It also has the function of I/O data logger, which can store I/O and GPS data in Micro SD card. The external and lithium battery connection interface is provided at the input of the power supply. After the external power supply is interrupted, the RTU-140 series can also operate for a period of time for emergency processing.
