Fast Ethernet Entry Line

Key Features:

Fast Ethernet Industrial Switches Entry Line
The fast Ethernet industrial switch entry line is not only a compact and flexible switch that can be extended to allow the extension of fiver ports but it is also simple to use as it can be operated Immediately without any configuration required.
This switch power supply is designed redundantly and equipped with an isolated alarm contact that reports a possible fault in the power supply of the device.

• Easy configuration, no extensive configuration
• 5x or 8x 10/100TX ports
• Version with fiber port for multimode and single mode
• 12 to 48 VDC power, redundant input
• Potential free contact indicates power loss
• Effective overvoltage protection
