Data Acquisition System


The Wireless Data Acquisition system can be used for monitoring maximum 400 distributed I/O endpoints through maximum 50 wireless Data Acquisition Modules by RF 433MHz wireless network. Also it can be used as for converting the meters, transducers, Data Acquisition modules, PLC data via RS485 serial port to 433 MHz wireless network and then transmits it to GSM / SMS / GPRS / 3G / Ethernet network. The range covers about 2~5Km, plus CC-02 Wireless repeaters can increase the wireless distance.
