8-Port RS-485 Hub

TD-1208 8-Port RS-485 Hub is a professional design for star-shaped wire layout in complex electromagnetic environment, RS-485 bus, large-scale systems. The RS-485 bi-directional transparent hub transmission, can divide one-way RS-232 bus or RS-485 bus into 8-way RS-485 bus, or put 8-way RS-485 signals all together to one-way RS-232 bus or RS-485 bus. And each port has optical isolation, short circuit, open circuit protection. In the system failure time, the built-in controller can cut off a timely faulty port, to ensure that every port of RS-485 Hub can work independently. every port can connect up to 32 nodes, extend the 1200 meters RS-485 signal. it is good choice to change the simple structure of RS-485 bus.
