The Yocto-PWM-Rx is a 2 channel PWM input. Each channel can report frequency, duty cycle, and pulse length. It works from 0.05Hz to 250Khz and accepts any -30..+30V signal as long as it crosses the 0.7V threshold.
Each channel also features a pulse counter linked to a time counter. This allows it to integrate over time the output of sensors such as flow-meters. The pulse counter works from 0 to 250kHz.
The two PWM inputs are galvanically isolated from the USB bus. This allows you to connect the Yocto-PWM-Rx to main-powered equipment without risking to fry your computer.
USB cables and enclosures to be ordered separately.
