LoRa network has become the most commonly used dedicated network communication technology for the Internet of Things due to its ease of construction and deployment. LoRa modules are widely used. A common RS232/RS485 line replacement solution is to replace the physical communication lines of devices or equipment in industrial or commercial applications with LoRa communication modules. Its original programs and functions do not need to be modified. , has the advantages of easy and fast layout and reduced installation costs.
ZHC00941/0951 is a remote I/O control device based on LoRa communication, which can realize point-to-point, one-to-many and other application scenarios. ZHC0941 provides 4 channels of dry/wet node detection and 4 channels of (4~20mA) analog input detection. ZHC0951 provides 4 channels of relay output and 4 channels of (4~20mA) analog output. The device supports Modbus RTU/TCP protocol for acquisition control and can be used in conjunction to achieve communication and I/O tracking between devices through the LoRa network.
