Further Expansion The PLC program can be further expanded to accommodate a
wide variety of commercial and industrial applications.
Start/Stop pushbuttons, selector switches, indicator lights, and
signaling columns can be added. Motor starters can be added
for control of additional motors. Over-travel limit switches can
be added along with proximity switches for sensing object
position. Various types of relays can be added to expand the
variety of devices being controlled.
As needed, expansion modules can be added to further
increase the I/O capability. The applications are only limited by
the number of I/Os and amount of memory available for the
PLC.
