Wiring Diagrams
The following illustrations show the wiring diagrams for the MicroLogix 1100
controllers. Controllers with DC inputs can be wired as either sinking or
sourcing inputs. (Sinking and sourcing does not apply to AC inputs.) Refer to
Sinking and Sourcing Wiring Diagrams on page 3-50.
The controller terminal block layouts are shown below. The shading on the
labels indicates how the terminals are grouped. A detail of the groupings is
shown in the table following the terminal block layouts.

TIP
This
symbol denotes a protective earth ground
terminal which provides a low impedance path
between electrical circuits and earth for safety
purposes and provides noise immunity
improvement. This connection must be made for
safety purposes on AC-powered controllers.
This
symbol denotes a functional earth ground
terminal which provides a low impedance path
between electrical circuits and earth for non-safety
purposes, such as noise immunity improvement.
