Chengdu Zongheng Intelligent Control Модуль DTU , the network is 4G full Netcom, providing 1RS485 and 1RS232. Its main feature is that it supports one-to-one and one-to-many networking. Can be used as a digital radio station. Using this function is very suitable for some small application scenarios, such as intelligent monitoring of water plants, community power resource management, smart air conditioning, etc. Anyone who purchases the Zongheng Intelligent Control DTU module can use Zongheng Cloud for free. Through Zongheng Cloud’s one-to-one networking, user costs can be saved.
In addition, this DTU module of Chengdu Zongheng Intelligent Control – (ZHC4012) also supports active data collection and uploading. It also supports adaptive Modbous RTU and TCP protocols, and can be connected to all mainstream configuration software. The above introduction is the special functions of this product.
DTU module features
1. Automatically collect sensor data and actively report it, eliminating the need for a collector, saving costs and reducing server pressure.
2. It can be used in point-to-point networking and point-to-multiple networking, supports digital radio function, is affordable and saves costs.
3. Support Modbus RTU/IP protocol adaptation, and also support http protocol. You can connect to some web management platforms.
Tip: This product is a DTU, which has relatively few functions. It requires AI, DI/DO interfaces, or local logic operations, threshold reporting and other functions. You can check out our company’s 4G RTU products.
Common functions of DTU module
1. Host and slave modes. The host mode supports RS485 cascading of multiple devices.
2. Adopt industrial-grade design, dual watchdogs, and anti-interference capabilities.
3. Transparent data transmission, both uplink and downlink, users do not need to worry about the communication protocol
4. Serial heartbeat package, registration package, etc.Also supports local upgrade and remote upgrade
