M-7084
4/8-channel Counter/Frequency/Encoder Input Module, communicates over RS-485 with Modbus RTU and DCON protocol, Operating Temperature -25 ~ +75°C
Features
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.
