What is the input voltage and frequency range of the eDAQ Plus’ pulse counter channels?

The frequency range is nominally 0.5 Hz to 50000 Hz for the MPB. At a frequency of 50000 Hz, the accuracy of the measurement is 1.0%. Frequency measurements at 5000 Hz are 0.1% accurate. (See TCE Help for detailed information on the various Pulse Counting Modes)
The input Voltage range of the Plus Processor’s Pulse Counter is 0.0 Volts to 5.0 Volts.
For signals larger than zero to five Volts, a Digital I/O Board is recommended.
