Plant/system-side signal voltages of 48V or 24V DC can be processed
using the interface module. The plant/system side of the module has 8
electrically isolated input channels. Using short-circuit connectors (X11),
the connection of each channel can be electrically isolated from one
another, or connected to a common reference point:

When supplied, all outputs have a common reference potential, i. e.
terminal pair X11 to X18 is equipped with two short-circuit connectors.
