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.
