• Subrack InterRail RFI The RFI-shielded version. The system dimensions of the InterRail subrack are based on those of the FLEXIBLE Fi as a logical further development to produce a subrack for heavy-duty use. This allows unrestricted use of the extensive range of accessories. The special design features of the InterRail subrack: •  Profile rails with a high section modulus guarantee resistance to vibrations. •  The refined RFI-shielding concept enables high shielding effectiveness (see the RFI-SHIELDED chapter).
