Mô tả
The UP-485-H4 is an industrial-grade 1-port RS-232/RS-485 to 4 ports RS-485 Hub/Splitter/Repeater with 2500V optical isolation, which can be used to expand RS-485 networks by splitting one RS-485 network into four, and extend the RS-485/422 distance up to 1.2km, effectively avoid damage caused by lightning strikes, surges and other factors.
UP-485-H4 adopts bus segmentation technology to realize star-type centralized network connection of RS-232/RS-485 devices and enhance bus signal load capacity, supports serial data rates up to 115,200bps, auto-sensing and self-adjusting, no DIP switch or jumpers are required, which widely used in intelligent power management, power system automation, water conservancy monitoring, industrial automation, distributed data acquisition and other occasions.
