F2164 GPRS RTU is a wireless Remote Terminal Unit(abbreviation: RTU).It has multiple functions (analog input,relay output,digital input,digital output,pulse counting and wireless data communication, etc).

It adopts high-powered industrial 32 bits MCU and embedded real time operating system. It supports RS232 and RS485 (or RS422) port which can conveniently and transparently connect devices to a cellular network, Easy to make your existing devices connect to network just with  basic configurations. It has low power consumption work mode in which the power consumption could be 1ower than 1mA@12VDC. It has compatible digital I/O channel, ADC, input pulse counter and pulse wave output functions.

It has been widely used in M2M fields, such as intelligent transportation, smart grid, industrial automation, telemetry, finance, POS, water supply, environment protection, post, weather, and so on.
