Isolating module

The following components are available as accessories for the F modules:

• Isolating module
  • Isolation of F and standard modules in an ET 200M remote I/O station
  • Signal isolation when using a copper bus connection (only F modules in an ET 200M remote I/O station with IM 153-2)
• Isolating bus submodule for isolating module, when using an active backplane bus

The isolating module is required in SIL 3 applications with F signal modules SM 326; AI 6 x 13 bit, SM 326; DI 8 x NAMUR and SM 326; DO 10 x DC 24 V/2 A (width 80 mm) in the following cases:

• Design of PROFIBUS DP with copper cables
• Design of PROFIBUS DP with fiber-optic cables and
  joint operation of the mentioned F signal modules with standard modules in an ET 200M station

Note:

The isolating module for F modules and the isolating bus submodule can only be used together. The 40-mm wide gap cannot be used for other modules.
