In fields such as industrial control, power communications, and smart instruments, serial communication is usually used for data exchange. The initial method used was the RS232 interface. Due to the complexity of the industrial site, various electrical equipment will produce a lot of electromagnetic interference

RTU (Remote Measurement and Control Terminal) is widely used in various industries such as building, HVAC, fire protection, water supply, petrochemical, environmental protection and other industries because of its telemetry, remote signaling, remote adjustment and remote control functions. However, as the control requirements increase, the

A relay is an electronic control device that has a control system (also called an input loop) and a controlled system (also called an output loop). It is usually used in automatic control circuits. It actually uses a smaller current to control a larger An

my country has heavy rainfall in summer, and flood control work in small and medium-sized rivers often becomes the focus of preventing floods during the rainy season. Therefore, in today’s highly developed Internet of Things technology, using Internet of Things technology to monitor small and

With the continuous development of the Internet of Things, more and more fragmented terminal devices realize network access. LoRa, as the most promising low-power wide-area communication technology at present, has been used in all walks of life. ZHC0561 and ZHC0661 are low-frequency (470~510MHz) half-duplex wireless

The rapid development of network and communication technology has provided RTU technology with more advanced and better performance, and has also brought wider applications to RTU products. In order to make it easy for beginners to use it, a simple RTU wiring tutorial will be

Industrial DTU products provide a wireless, non-regional restricted data transmission and networking solution for various sensor devices and other terminals that require data transmission. The following article will briefly introduce several common DTU networking methods. 1. The process of data collection and transmission After the

Wireless data transmission DTU is a transmission device that uses the cellular networks of major operators to transparently transmit the data collected at the front end to the remote control center without loss. It can complete functions such as real-time data collection, remote data transmission,

Zonghengyun transparent transmission function can support remote control of DTU / RTU equipment without public network IP, which facilitates customers to quickly test and understand product functions and greatly shortens the development cycle. This document uses ZHC4921 as an example. Products of the same type

With the rapid advancement of industrial informatization, remote data collection and equipment monitoring through the network have become the most economical and reliable way. Ethernet network IO relays are widely used in industrial automation, intelligent building monitoring, power systems, unattended parking lots, etc. It has

4G DTU functions as a data pipe transmission in the Internet of Things system. It uses the 4G network of TD-LTE or FDD-LTE to realize wireless long-distance data transmission between the local serial port and the remote public network server. It is mainly used for

The Chinese name of DTU is wireless data transmission terminal. It is an Internet of Things device specially used to convert serial data into IP data or convert IP data into serial data for transmission through a wireless communication network. DTU features DTU uses a
