1 - 54 Modular LYNX System 12.05.2003
Input Filtering

User definable Digital filtering makes the LYNX well suited for noisy industrial environments. The filter

setting is software selectable using the IOF Variable with a minimum guaranteed detectable pulse width of

18 microseconds to 2.3 milliseconds.

The table below illustrates the IOF settings.
