The GSM-ALARM272 4G LTE IoT M2M RTU is an industrial grade, high reliability, high stability and programmable Remote Terminal Unit (RTU).
The RTU has 8 digital inputs, 6 analog inputs, 4 relay outputs, 1 external sensor input for monitoring temperature and humidity.
1 x RS485 serial port. As a Modbus master, the RTU can be connected to expansion I/O modules or read data from instruments, PLCs and other devices.
Users can set high and low limits according to different application scenarios, when the alarm occurs RTU will notify users via SMS, call and also upload data to cloud platform, monitoring center.
The RTU can also be used as a remote switch, remote I/O, remote smart PLC, timer switches, which are able to open the gate or turn on the machine with a free call at a specific time to save time
for daily maintenance.
The RTU supports 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, safety monitoring system, automatic measurement and control system, BTS monitoring, remote data collection, telemetry systems,
automatic control system.
