Product Overview

EISK switches provide Plug and Play Ethernet connectivity for industrial automation systems which have unique requirements—convenient mounting, simple and dependable operation, low-voltage input power and especially cost-effective. These needs are met by the compact and rugged Skorpion family.

Utilizing state-of-the art switching technology, the Skorpion family of 5- and 8-port switches provides copper-only and copper fiber combinations. Copper ports provide auto-negotiation of data rates at 10 or 100 Mbps. All copper ports support half-duplex operation with backpressure flow control or full-duplex operation with PAUSE control. All copper ports are Auto-MDIX compliant, eliminating the need for crossover cables.

Fiber ports are used when distances exceed the 100 meter limit of copper, when immunity to EMI/RFI is important or for additional communication security. ST or SC connectors are available for use with (1300 nm) multimode fiber cable to span to 2000 meters or SC connectors with single-mode (1300 nm) fiber cable to extend segment lengths to 15,000 meters. All fiber ports operate at 100 Mbps full-duplex.

Skorpion Switches address the problem of convenient mounting in control panels where DIN-rail space is at a premium. Office-grade equipment is intended for desktop operation and requires a separate power supply that needs to be powered from a 120/230 Volt AC mains circuit. In this case, a shelf should be constructed to mount the unit and a duplex receptacle to be installed inside the control panel. Skorpion Switches are intended for sub-panel mounting inside the control panel. Switches are intended for sub-panel mounting and can be powered from the same control transformer that is used to power the industrial automation system equipment. Skorpion Switches can be powered from a low-voltage, wide range AC or DC power source as well. The activity LEDs on these units face the technician, thus easing trouble-shooting. The label on the unit can be written upon so port connections can be documented as to the location of connected equipment.

The auto-negotiation protocol allows Skorpion Switches to link with any compatible 10BASE-T or 100BASE-TX device. They will function with any application layer that works with Ethernet, including Modbus/TCP or Ethernet/IP. These units have built-in broadcast storm control to prevent excess broadcasts from degrading network performance.
