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:
