IoT relay
A series of IoT relays developed by Zongheng Intelligent Control include network relays with network transmission and extended interface network relays, which are commonly used for automatic control, automatic switching, automatic adjustment, conversion, etc. Most of Zongheng Intelligent Control’s network relays support wet and dry node detection, local logic operations, multi-channel sockets, and are compatible with Modbus RTP/TCP protocols.
Provides a variety of network types for users to choose from, including 4G full network, GPRS network, Ethernet, and LoRa network. Our company’s products take “remote control” as the core function and are highly easy to use. Users can easily and quickly integrate them into their own systems.
