The M-7084 is a 32-bit high-speed Counter/Frequency/Encoder input module that
offers a variety of mode options, including "Up Counter”, "Frequency Input",
"Up/Down Counter", "Direct/Pulse Counter" and "A/B Phase Counter" modes. The
mode combinations can be individual set for all 8 channels, where some channels
can be set to “Up Counter” mode and other channels can be simultaneously set to
“Frequency”, "Up/ Down Counter" or “Encoder input” mode. The built-in digital fi
lter can fi lter out noise where the high/ low pulse width is smaller than the
minimum high/low width of the digital filter. The M-7084 provides a virtual
battery backup function in counter mode.
