1 - 50 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 millisec-
onds.
The table at right illustrates the IOF settings.
