Description
3500 Internal Barriers are intrinsically safe interfaces that
provide explosion protection for transducer systems connected directly to the 3500 Machinery Protection System.
The internal barriers are fully compatible with the 3500 System and provide a convenient and cost-effective solution
for installing all types of transducer systems within a hazardous area.

I/O Module Positioning
Internal barrier I/O modules have an increased depth over that of standard barrier I/O modules. Consider the rack position with
respect to adjacent modules to ensure that you can easily access the I/O modules during maintenance.
Internal barrier I/O and IS Earthing modules can occupy any general-purpose rack position and can be adjacent to standard I/O module types
without compromising the 50 mm (2 in) physical separation requirement between safe and hazardous area field wiring.
Follow these guidelines when positioning I/O modules:
l Group all internal barrier I/O modules in adjacent rack positions to simplify the installation. l Place the IS Earthing Module in a rack
position that provides easy access for routine online maintenance.
l Consider the IS Earthing Module’s positioning relative to adjacent internal
barrier I/O modules and cabinet bulkheads.
