LRS-24 Module Slots
The LRS-24F enclosure has a lower section for the functional modules and a top
section for interface modules. The LRS-24B enclosure has a front section for the
functional modules and a rear section for interface modules.
Each section has 15 module slots:
• Two slots are reserved for PS modules.
• One slot is reserved for the common logic module (CM-1 or CM-2).
• The other 12 slots are intended for user (I/O) modules. Each I/O slot can
accept any type of I/O module. The modules are inserted from the front side.
The top section of LRS-24F (back section of LRS-24B) includes slots for the
interface modules.

Figure 1-7 shows a typical front view of the LRS-24F enclosure, and identifies the
slots and their use. Note the labels that designate the type of module that can be
