Description
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 filter can filter 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.
