Product Introduction
Summary
ZLAN9440 is a 4 ports industrial isolation RS485 hub, can extend 4 channels RS485 sub-ports through 1 channel RS485/232 main port. It can effectively implement reply, extension and isolation of RS485 network. ZLAN9440 can also be as an active isolation RS232 to RS485 converter. If you only need 1 channel the model is ZLAN9410.
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.
ZLAN9440 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.
ZLAN9440 has 4 main application styles:
1) Isolation: effectively isolate master and slave ends of RS485 network; meanwhile isolate 4 slave stations.
2) Relay: can effectively extend communication distance of RS485 network.
3) Extension: can implement 1 channel RS485 extending to 4 channels RS485, multiply the numbers of RS485 devices in the network.
4) Conversion: also can realize 1 channel RS232 converting to 4 channels RS485.
Feature
1) RS485 master port and slave port has 2500V voltage isolation protection.
2) RS485 master port and slave port support 256 slave stations.
3) The back is equipped with guide installation card slot, suitable for guide installation.
4) 9~24V wide range input.
5) RS485 opposite connection indicator. The CH1~CH4 indicator is always on when line A and line B are opposite connected.
