Description

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.

The ET-7284/PET-7284 module is equipped with FRAM memory to retain the counter values. FRAM is a type of non-volatile memory that can be used to store written data, even after the module has been powered off. This storage feature can be either enabled or disabled, and the data can be retained for up to 10 years.
