Cellular IoT M2M RTU --- S272/S274/S275
1 Introduction
1.1 Overview
The Cellular IoT M2M 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 Cellular module. The RTU features 8 digital inputs, 6 analog inputs, 4 relay outputs, 1
ambient sensor input for monitoring onsite temperature and humidity, and 1 RS485 serial port. And as
Modbus master, the RTU can connect to expansion I/O module or read data from instruments, PLC
and other devices.
Users can set high and low limit according to different application scenarios, when alarm occurs, the
RTU will notify users by SMS, dialing, and also uploading data to cloud platform, monitoring center.
The RTU also can be used as a remote switch, remote I/O, remote smart PLC, timer switches, which
is able to open the gate or turn on the machine with a free charge call at specified time to save time
for daily maintenance.
The RTU supports BLIIoT IoT RTU protocol, Modbus RTU over TCP protocol, Modbus TCP protocol,
MQTT protocol, which can communicate directly with the server, cloud platform or SCADA. It is a cost
effective IoT solution for industrial automation, security monitoring system, automatically
measurement and control system, BTS monitoring, remote data acquisition, telemetry systems,
automatically control system.
1.2 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
