Details

HUB RJ91G-485 is designed to solve the complex electromagnetic field environment under the RS-485 large system requirements and design of the RS-485 bus division hub (HUB). RS-485 bus segmentation hub (on) the product support transmission rate up to 115.2KBPS. In order to ensure the safety and reliability of the data communication, RS-485 interface terminal using photoelectric isolation technology, to prevent lightning surge into the converter and equipment, built-in optoelectronic isolator and 1500W surge protection circuit to provide 2500V isolation voltage, can effectively inhibit the lightning (lighting) and ESD, and can effectively preventing lightning and total interference, is powered by an external switch power supply, safe and reliable, very suitable for outdoor application.

In RS-485 working mode, the discrimination circuit can automatically detect the direction of data flow, and automatically switch the control circuit, so that it can easily solve the problem of RS-485 transceiver conversion delay. RS-485 interface transmission distance greater than 1200 meters, stable performance. Widely used in highway toll collection system, road monitoring system and power acquisition system, is an excellent performance, excellent price data interface conversion products.

HUB RJ91G-485 provides star RS-485 bus connection. Each port has a short circuit, open circuit protection. Opticalisolation 2500V, users can easily improve RS-485 bus structure, division of network, improve the reliability of communication. When a fault or lightning equipment, network problems will be isolated, to ensure the normal work of the other segment. This performance greatly improves the reliability of the existing RS-485 network, and effectively shorten the maintenance time of the network. Rational use of HUB RJ91G-485 can help you to design a unique and highly reliable RS-485 system.
