Cellular IoT M2M RTU

The Cellular IoT Modbus RTU is an industrial class, high reliability, high stability, and programmable Remote Terminal Unit (RTU).
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 water sensors, power sensors, PLC and other instruments.
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 systems.

Inbuilt inter-lock logic programmer and powerful timer program function;
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.

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.

Metal case with IP30 protection grade, safely isolated from inner system, especially suitable for industrial control application.
