Cellular IoT Gateway
1. Brief introduction
The Cellular IoT Gateway S17X/S37X is an industrial class, high reliability, high stability, and programmable Remote
Terminal Unit (RTU). It embedded 32-Bit High Performance Microprocessor MCU, inbuilt industrial Cellular
module. It provides 1 ambient sensor input for monitoring onsite temperature and humidity, and RS485 serial port,
supports 128/224/320 mapping registers via Modbus RTU protocol. It can monitor and operate the I/O ports by
SMS, APP, Web Server, internet, timers and programmed inter-lock events automatically.
The Cellular IoT Modbus Gateway S17X/S37X 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 Ethernet or 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 Gateway S17X/S37X is designed 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 RS485 data transmission, remote extend I/O tags control, remote smart
PLC, meters monitoring.
The Cellular IoT Modbus Gateway S17X/S37X supports 2 RS485 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. 2 RS485 ports
can be used one as Modbus RTU Master and the other as Slave at the same time.
Typically applications:
BTS Monitoring, Security Alarm System applications, Supervision and monitoring alarm systems, Automatic
monitoring system, Vending Machines security protection, Pumping Stations, Tanks, Oil or Water levels, Buildings
and Real Estate, Weather Stations, River Monitoring and Flood Control, Oil and gas pipelines, Corrosion protection,
Temperatures, water leakage applications, Wellheads, boat, vehicle, Energy saving, street lights control system,
Valve controls, Transformer stations, Unmanned machine rooms, Control room application, Automation System,
M2M, etc.
