Description:
JPX-6041 is an RS-485 bus splitter hub (HUB) designed for industrial automation communication, which solves the RS-485 bus star structure networking and solves the RS-485 large system requirements in complex electromagnetic field environment. Support The transmission rate is up to 115.2kbps, the RS-485 interface uses optical isolation technology, 600W lightning surge protection circuit, provides 2500V isolation voltage can effectively buckle lightning and ESD protection. The discriminating circuit used in RS-485 working mode can automatically Perceive the direction of data flow, and automatically switch the enable control circuit to easily solve the RS-485 transceiving conversion delay problem. The RS-485 interface transmission distance is greater than 3000 meters and the performance is stable. Widely used in highway toll collection systems, road monitoring systems and power collection systems, it is a data interface conversion product with excellent performance and excellent price.
