ESP32 WiFi wireless module 4 digital input output remote relay control unit industrial controller with alarming timing
WIFI RTU product overview
WiFi RTU is a collection and control terminal device that uses WiFi wireless data transmission.The device uses ESP32 module, supports more free development and more flexible scenario applications, supports TCP, UDP, network protocols, and provides users with fully transparent data transmission mode.Support custom heartbeat package, registration package, data guide package, support through mountain cloud port, users do not need to set up a server, fully support industrial configuration application, users do not need to care about the complex network protocol, through the transparent serial port, you can send and receive wireless data, so that your device can access to the Internet anytime and anywhere.
WiFi RTU supports TCP and UDP message formats, which can be selected by users at will.The 4-way analog output, 4-way switch output and 4-way relay output are suitable for most application scenarios and can solve the problem of data transmission for you without any wiring.WiFi RTU provides wireless data transmission and acquisition control wherever there is a WiFi network.
