The MicroLogix 1400 provide discrete I/O and analog input that is built
into the controller as listed in the following table. These I/O points are
referred to as Embedded I/O.

AC embedded inputs have fixed input filters. DC embedded inputs have
configurable input filters for a number of special functions that can be
used in your application. These are: high-speed counting, event input
interrupts, and latching inputs. The 1766-L32BXB and 1766-L32BXBA have
three high-speed outputs for use as pulse train output (PTO) and/or pulse
width modulation (PWM) outputs.
