ZLAN9480A is an 8 ports industrial isolation RS485 hub, can extending 8 channels RS485 slave ports through 1 channel RS485 master port. It can effectively implement relay, extension and isolation of RS485 network.

The master-port end of ZLAN9480A provides isolation RS485, the slave-portend extends 8 channels isolation RS485 interface.

The main port of ZLAN9440 provides isolation two interface RS485 and RS232 at the same time, the sub-ports extend 4 channels isolation RS485 interface.

Generally the RS485 wiring require hand-in-hand wiring style, need avoid star connection of master station as center. But sometimes need star connection, in this case using RS485 hub can effectively isolate connection interference between multi-RS485.

ZLAN9480A is active isolation RS485 hub, the product are specially designed for industrial scene in harsh environment, is especially suitable for situations requiring high reliability and safety. The photoelectric isolation function can effectively make master and sub devices separate from each other, avoid damage from ground potential difference of master-slave devices and static, lightning, surge to devices, also can avoid damage from ground loop current caused by ground potential difference.

ZLAN9480A has 3 main application styles:
1) Isolation: effectively isolate master and slave ends of RS485 network; meanwhile isolate 8 slave stations.
2) Relay: can effectively extend communication distance of RS485 network.
3) Extension: can implement 1 channel RS485 extending to 8 channels RS485, multiply the numbers of RS485 devices in the network.
