Description
Overview
GAOTek IoT telemetry termina with industrial grade design 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 limits according to different application scenarios. When an 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 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.
