Basic Information

Dimensions: length 17.8cm, width 10.2cm, height 22.9cm, weight 2.1kg.

Place of Origin: Originally from Sweden.

Functional characteristics

Optical and electrical conversion function: mainly to achieve mutual conversion between optical and electrical signals, so that optical signals transmitted based on optical fibre can be seamlessly connected with electrical signals of control system or field equipment, to ensure the accurate transmission of data between different transmission media.

High-speed data transmission: Using advanced optical fibre communication technology, it supports high-speed data transmission, which can meet the demand of industrial automation control systems for fast and stable transmission of large amounts of data, and effectively improve the system's operational efficiency and response speed.

Multiple interface support: Equipped with a variety of different optical fibre interfaces and digital interfaces, it can connect and communicate with various types of equipment and systems, such as PLCs, DCSs, sensors, actuators, etc. of different manufacturers, which enhances the compatibility and versatility of the equipment.

Powerful data processing capability: adopting high-performance processor and digital signal processing technology, it can quickly process various data and signals, amplify, shape and filter the signals during transmission to improve the signal quality and ensure the stability and reliability of the system.

Reliability design: industrial-grade components are selected, and through strict quality control, it can work stably under harsh environmental conditions, such as high temperature, high humidity, strong electromagnetic interference and other environments, reducing the probability of equipment failure and data transmission errors.

Expandability: With modular design, it is convenient for users to expand and upgrade the system according to the actual demand, and it can flexibly increase or decrease the communication ports, function modules, etc., which improves the maintainability and expandability of the system.

Working Principle

In INFI-Net network, NTCF22 firstly receives the optical signals from the optical fibre network, and converts the optical signals into electrical signals through the internal optoelectronic converter module, and then processes the electrical signals, such as filtering, amplifying, shaping, etc., in order to improve the signal quality. The processed electrical signals are transmitted to the control system or field devices. On the contrary, when it is necessary to transmit the electrical signal to the optical fibre network, NTCF22 first receives the electrical signal from the control system or field equipment, processes it, and then converts the electrical signal to optical signal through the internal electro-optical converter module, and finally sends the optical signal to the optical fibre network for transmission.
