Giới thiệu
GT-540-3GWA is an intelligent Active 3G Remote Terminal Unit. Within the high performance 32 bit CPU, GT-540-3GWA is suit for the hard industrial environment. It features 3G(WCDMA) module, 6 digital inputs, 2 digital outputs, 1 analog input, 1 RS-232, 1 RS-485 and SD interface. It can be used in M2M application fields to transfer the local I/O or Modbus device's data via GPRS by the defined period or DI/AI triggers. The local I/O data can also be stored in the SD card to become a remote data logger. For another communication path, GT-540-3GWA offers the e-mail mode to transfer the data by e-mail via 3G for users to choose. The simple I/O linkage function of GT-540-3GWA can reach the real time control in local field. It also supports Li-ion battery as another power source when the main power is failed temporarily. Therefore, GT-540-3GWA is an ideal solution for environmental monitoring and remote device management for M2M applications. Meanwhile, it is supplied with easy-to-use API and OPC server Software that streamline application development process, freeing system integrators from dealing with complex communication protocols of 3G and the Internet.
