The modules are designed as plug-in PCBs for central controllers and
expansion units with a backplane connector and with a blade
connector to accept a plug-in front connector. You can directly
connect the process signal lines to the front connector, which is
available separately, with screw or crimp terminals.
Situated on each module is an addressing switch with six rockers to
set the module address. Analog input modules also have two switches
on the side with eight rockers for setting the mode, and receptacles for
range cards.
The modules are protected by covers on both sides.
