Cellular IoT Modbus RTU (8DI,6AI,4Relay,1TH,USB,RS485,320 Extend I/O tags)

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.
