Import S278 Cellular Iot Modbus Gateway — Buy in wholesale FOB from Supplier in China

Model:S278 Name: Cellular IoT Modbus Gateway The Cellular IoT Modbus Gateway is an industrial class, high reliability, high stability, and programmable Remote Terminal Unit (RTU). It embedded 32-Bit High Performance Microprocessor MCU, integrated 1 Industrial 10/100M adaptive Ethernet module inside and inbuilt industrial Cellular module. It provides 4 digital inputs, 2 relay outputs, 1 ambient sensor input for monitoring onsite temperature and humidity, and RS485 serial port, performs as Modbus RTU Master Supports extend maximum 320 mapping registers. It can monitoring and operates the I/O ports by SMS, APP, Web Server, internet, timers and programmed inter-lock events automatically. The Cellular IoT Modbus Gateway supports transparent data transmission and performs as Modbus Slave over GPRS/3G/4G/NB-IoT network and RS485 serial port. Moreover, the Cellular IoT Modbus RTU can be used as Modbus RTU Master to reading smart meters, I/O modules, PLC, and converts to SMS alert once triggered the threshold value, or transmit data to remote server over GPRS/3G/4G/NB-IOT network.
