The Cellular IoT Modbus RTU 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.
The Cellular IoT Modbus RTU is an industrial class, high reliability, high stability, and programmable Remote Terminal Unit (RTU). It embedded 32-Bit High Performance Microprocessor MCU, inbuilt industrial C
ellular module. It provides 8 digital inputs, 6 analog or PT100 Resistance Temperature Detector (RTD) inputs, 4 relay outputs, 1 ambient sensor input for monitoring onsite temperature and humidity, and RS485
serial port, supports 320 mapping registers via Modbus RTU protocol. 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 RTU inbuilt TCP/IP protocol stack make it suitable for internet of things (IoT) applications, it can be easily to operate by the provided cloud, app, and web server, or integrated to you IoT applications
according to the TCP/UDP protocol, or integrated to SCADA systems by standard Modbus TCP protocol, too. This is very useful if you need remote control onsite devices with low cost solution.
The Cellular IoT Modbus RTU is design for working in the harsh industrial application environment, widely used in a variety of industrial automation, security monitoring system, automatically measurement and control
system, BTS monitoring, remote data acquisition, telemetrically systems, automatically control system. It can be used as a remote switch, remote I/O, remote smart PLC, timer switches.
The Cellular IoT Modbus RTU can be used as remote access control for BTS monitoring, the authorized users can open the gate or turn on the machine with a free charge call at specified time, this is useful for daily
maintenance to save the time of traditional authorized.
The Cellular IoT Modbus RTU 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
