Description / Industrial Counter Bricklet
The Industrial Counter Bricklet can be used to extend Bricks by four frequency counter channels.
The Bricklet has an integrated edge counter and it can measure duty cycle, period, frequency and value per channel. The frequency can be as high as 4MHz.
The edge counter can count rising edges, falling edges or both. The direction of the count (up or down) is configurable. It is also possible to use the value of one channel as the direction (e.g. high = up, low = down) for another channel.
All 4 channels are galvanically isolated.
Example applications for the Bricklet are reading of a PWM signal and reading of sensors that have edge counts or frequency as output.
