PET-7284_DESCRIPTION.html
The ET-7284/PET-7284 is a 32-bit high-speed Counter/Frequency/Encoder input and 4-channel Digital Output module that offers a variety of input mode options, including "Up Counter", "Frequency Input", "Up/Down Counter", "Direct/Pulse Counter" and "A/B Phase Counter". The mode can be individually configured for all 8 channels, where, for example, some channels can be set to "Up Counter" mode, and other channels can be individually set to "Frequency", "Up/ Down Counter" or "Encoder input" mode. The built-in programmable low pass filter can be used to eliminate noise where the width of the high/low pulse is narrower than the minimum high/low width of the low pass filter.
