I.Product OverviewYT-602 is an RS-485 repeater, bus extension, and split hub (HUB) designed specifically to meet the requirements of RS-485 large systems in complex electromagnetic field environments. This product supports a transmission rate of up to 115.2KBPS. In order to ensure the safety and reliability of data communication, the RS-485 interface adopts photoelectric isolation technology to prevent lightning surges from being introduced into the converter and equipment. The built-in photoelectric isolator and 600W surge protection circuit can provide an isolation voltage of 2500V, effectively suppressing lightning and ESD, and effectively preventing lightning strikes and common ground interference, The power supply adopts an external switch power supply, which is safe and reliable, and is very suitable for outdoor engineering applications. In the RS-485 working mode, the discrimination circuit used can automatically sense the direction of the data flow, and automatically switch the enabling control circuit, easily solving the problem of RS-485 transmission and conversion delay. The RS-485 interface has a transmission distance greater than 1200 meters and stable performance. Widely used in highway toll collection systems, road monitoring systems, and power acquisition systems, it is a high-performance and cost-effective data interface conversion product.
YT-602 RS-485HUB provides star shaped RS-485 bus connection and extension. Each port has short-circuit and open circuit protection. Optoelectronic isolation of 2500V allows users to easily improve the RS-485 bus structure, divide network segments, and improve communication reliability. When lightning strikes or equipment malfunctions occur, the problematic network segment will be isolated to ensure the normal operation of other network segments. This performance greatly improves the reliability of existing RS-485 networks and effectively shortens network maintenance time. Reasonable utilization of 602RS-485HUB can help you design a unique and highly reliable RS-485 system.
