Product overview

CWT4421 IoT gateway with 4DI, 2DO, 4AI, RS485 standard electrical interface can connect various industrial equipment, such as PLC, meters, sensors, electrical
switches. It monitors the industrial system real-time running status and data, as well as constructs the remote device to a proprietary central computer and mobile phones through the 4g or Wi-Fi communication network. It efficiently acquires the remote equipment operating parameters and process management, can be widely used in industrial automatic control, base station / computer room monitoring, environmentalmonitoring, water conservancy project, powerindustries,

agriculture, etc.

CWT Cloud Summary

CWT cloud is anindustrial equipmentmanagement system based on internet, cloud computing.

With CWT RTU, CWT cloud can get status, value, position of remote industrial equipment, built a very complete M2M, M2H industrial ecosystem.

CWT cloud can manage thousands CWT RTU remotely, display all industrial equipment real-time data, location tracking, control device, send commands and store data, analysis data, export data. Operations are based on internet, just login cloud via PC browser or cell phone app to do.
