BENTLY NEVADA | 136703-01 | I/O MODULE INTERNAL BARRIER

Product Discription

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.
