Industrial Rail 8FE+2RS232+2SFP Ring Network Ethernet Switch

Type:ERING-FG2F8R2 Message

Description: 8*10/100M electrical port +2*RS RS232/422/485+ 2*Gigabit optical ring port， SFP Fiber moudle,console, SNMP, Industrial Rail or wall mounted.

Product Description
   This series of products using industrial rail design, each device 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.

Functional Properties
