Managed Din-Rail 8-Port 10/100M Ethernet + 2-Port Gigabit SFP + 2-Port Serial Ring Network Industrial Switch

View : 234
Type : Ethernet + Serial Data Industrial Switch
Description :

This product offers: 2 Gigabit SFP optical ports; 8 electrical Fast Ethernet interfaces, 2 RS232/422/485 serial ports.


This product uses industrial rail design, it has two fiber-optic ports for ring network to achieve in a harsh environment, the stability of data transmission, reliability and timeliness. Work network signal into a chain structure, but simplifies installation and reduces the cost of the project.

This product offers: two Gigabit SFP optical ports; eight electrical Fast Ethernet interfaces, 2* RS232 / 422/485 serial port. 2 serial ports is individually designed, each serial port-based design, one is the master control node, the other all slave nodes.
