1-2 I/O Configuration
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
interrupts, and latching inputs. The 1764-28BXB has two high-speed
outputs for use as pulse train output (PTO) and/or pulse width
modulation (PWM) outputs. The 1762-L24BXB and -L40BXB each have
one high-speed output.
