Even though modules may be supplied with power from the
IMPORTANT
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.
