Product Description:

UT-1208 is a dual-core inside, round design (uninterrupted work), designed to solve complex electromagnetic environment RS-485 system requirements and design of the RS-485 bus split hub (HUB). The product supports transfer rates of up to 115.2KBPS, in order to ensure safety and reliability of data communication, RS-485 interface port with optical isolation techniques to prevent the introduction of lightning surge converters and equipment, built-in optical isolator and 1500W surge protection circuit able to provide 2500V isolation voltage, can effectively inhibit lightning (Lighting) and ESD, and can effectively prevent the interference of lightning strike and common external switching power supply with power supply, safe and reliable, ideal for outdoor engineering applications. 
 

In RS-485 mode, the discrimination circuit can automatically sense the direction of the data flow, and automatically switches to enable control circuit, easily solve the problem of the RS-485 transceiver conversion delay. RS-485 interface transmission distance is greater than 1200 m, and stable performance. Widely used in highway toll collection system, road monitoring systems and power collection system is a high performance, excellent price data interface conversion products. 

UT-1208 RS-485 HUB provides the star RS-485 bus connection. The port has a short circuit, open circuit protection. Optical isolation 2500V, users can easily improve the structure of the RS-485 bus split network segment to improve communication reliability. When lightning strikes or equipment failure occurs, the problem segment will be isolated to ensure the normal work of the other segment. This performance is greatly improved the reliability of the existing RS-485 network, which effectively shorten the time of network maintenance. Reasonable use of UT-1208 RS-485 HUB can help you design a unique and highly reliable RS-485 systems.
