Product Description
Product Description:
ATC-1204 is a RS-485 bus split hub specially designed. To meet the demand of RS-485 system in complicated electromagnetic field environment. The product supports maximum 115.2KBPS transmission speed. The RS-485 interface has adopted photoelectric isolation technology to ensure safe and credible data communication, and prevent inducing lightning strike and surge to conversion board and devices. The built in photoelectric isolator and 600W surge protection circuit can offer 3500V isolation voltage, effectively inhibit lightning and ESD and prevent lightning strike and common code interference. It has adopted external switch power supply, safe and credible, quite suitable for outdoor engineering application.
In RS-485 working mode, the adopted identification circuit can detect data direction and switch to control it automatically, easily to solve the time lag of RS-485 during receiving and conversion. The transmission distance of RS-485 interface has exceeded 1200 meters with stable performance.
It is a data interface conversion product with superexcellent performance and good price and can be widely applied to freeway charge system, road monitoring system and electric power collection system.
ATC-1204 RS-485 HUB offers star type RS-485 bus connection with each port equipped with short/open circuit protection. With 3500V photoelectric isolation, the user can easily improve RS-485 bus structure, split net segment, and enhance communication credibility. When lightning strike or device malfunction occur, the troubled net segment will be isolated to ensure the normal function of others, which has greatly enhanced the credibility of existing RS485 network and effectively shorted network maintaining time. Reasonable use of ATC-1204 RS-485 HUB can help you design a unique and highly credible RS-485 system.
