JXQ Series RS485 Hub

JXQ series RS485 hub is a RS-485 bus splitter designed to address the requirements of large RS-485 systems in complex electromagnetic environments. The product supports transmission rates up to 115.2Kbps. To ensure safe and reliable data communication, the RS-485 interface uses optical isolation technology to prevent lightning surges from introducing into the converter and equipment. The built-in optical isolator and 1500W surge protection circuit provide 2500V isolation voltage and effectively prevent lightning, ESD, and grounding interference. The power supply uses an external switching power supply for reliable operation. In the RS-485 mode of operation, the discrimination circuit automatically senses the direction of data flow and switches the enable control circuit automatically, solving the delay problem of RS-485 transceiver conversion easily. It is widely used in power collection systems and is a high-performance and cost-effective data interface conversion product. JXQ serie
