Housings
The PLC' s systems use Modicon 800 series housings for its controller and l/O
modules; specifically, a 19" primary housing which holds seven modules or a 27"
primary housing which holds eleven modules.
Primary Enclosure - With the single-width controllers mounted in your primary en-
closure, the 19' and 27" primary enclosures will hold up to 6 or 10 I/O modules re-
spectively.
Secondary Enclosure-The remaining secondary housing will accommodate a
one and one-half wide P810, P800 or P884 auxiliary power supply if a power sup-
ply expander is required. That is, the standard 19" or 27" secondary housings will
accommodate five or nine I/O modules along with a one and one-half wide (two-
slot) auxiliary power supply and a full seven or eleven I/O modules without the
power supply.
The 19-inch primary housing with controller is shown in Figure 5. For simplicity' s
sake, the 27" housing is not shown in this manual except as required in the
illustrations for panel mounting dimensions.
