Functionality

Optical fibre communication function:

High-speed and stable transmission: adopting optical fibre as the communication medium can achieve high-speed and stable data transmission. Compared with the traditional electrical signal transmission, optical fibre has higher bandwidth and lower signal attenuation, which can ensure the fast and accurate transmission of large amounts of data between remote devices, and meet the requirements of industrial automation systems for real-time and reliability.

Strong anti-interference ability: As optical fibre transmits optical signals, it is not affected by electromagnetic interference, so in the industrial field, even if there is a large number of electrical equipment generating electromagnetic noise, it can ensure the quality of the signal transmission, effectively reducing the error rate of data transmission, and improving the stability of the system.

Remote I/O Function: As a remote I/O terminal unit, it can connect various input/output devices in the field, such as sensors and actuators, with the central control system. It can receive signals from field devices and convert them into digital signals for transmission to the central control system; at the same time, it can also convert the control signals issued by the central control system into signals suitable for field devices to achieve remote control and monitoring of field devices, greatly expanding the coverage of the control system, and facilitating the centralised management and control of devices distributed in different locations.

Power distribution function: provide stable power supply for the connected remote I/O devices, reduce the dependence of field devices on external power supply, simplify the power wiring of the system, and improve the integration and reliability of the system.

Application Fields

Power industry: Widely used in power plants, substations and other places to achieve the monitoring and control of remote equipment. For example, connecting remote power measuring instruments, protection relays, intelligent switches and other equipment, and transmitting the operating status and measurement data of the equipment to the central control system, so that operators can grasp the operation of the power system in a timely manner, carry out effective scheduling and control, and ensure the safe and stable operation of the power system.

Chemical industry: In the chemical production process, it is used to connect chemical production equipment, sensors and actuators distributed in different areas. For example, it can remotely monitor the temperature, pressure, liquid level and other parameters of the reaction kettle, control the opening of valves, start and stop of motors, etc., so as to realise the automation control and optimization of the chemical production process, and improve the production efficiency, product quality and production safety.

Metallurgical industry: It can be applied to the automation control system of metallurgical plants, connecting the control system and monitoring equipment of rolling mills, furnaces, cranes and other equipment. Through the remote I/O terminal unit, it can realize remote operation and status monitoring of these equipments, ensure the smooth running of metallurgical production process, improve production efficiency and product quality, and reduce labour cost and labour intensity.

Pharmaceutical industry: In the pharmaceutical production line, it connects the control system and monitoring sensors of various pharmaceutical equipments, such as the temperature and stirring speed control of the reaction tank, and the operation status monitoring of the pharmaceutical packaging equipment. To achieve precise control and quality monitoring of the drug production process, to ensure compliance and quality stability of drug production, to meet the strict requirements of the pharmaceutical production quality management standards.

Food and beverage industry: used for food and beverage processing and packaging process equipment connection and control. For example, remotely controlling the temperature and time parameters of food processing equipment, monitoring the operating status of packaging equipment, etc., to improve production efficiency and product quality, while ensuring that the production process meets health and safety standards.
