Publication 1797-5.34 - September 2011
Make certain that you only connect intrinsically-safe power supplies to other
intrinsically-safe system modules or adapters to maintain the integrity of the
intrinsically-safe backplane.
IMPORTANT
Even though modules may be supplied with power from the same
power supply output channel, galvanic isolation in the module
provides module-to-module galvanic isolation. Depending upon the
module type, galvanic isolation (channel-to-channel within the
module) may or may not be provided. See the module’s
specifications for more information.
