The ISFE-5 intrinsically switch enables communication in 10/100BaseTx/ 10/100BaseFx standard. The device enables communication both via fiber optic cables (sigle or multimode) and via copper twisted pair. The device is equipped with five Ethernet ports. The communication status at each port are presented by the LED diodes.

The intrinsically safe switch module provides „ia” explosion protection level.

  • possible combinations of devices with different network interfaces
  • two-way conversion between the copper interface and the fibre optic interface
  • operation status signalling (LED diodes)
  • optional transmission over single optical fiber (using BiDi SM transceivers)
