Image 3.3: Digital inputs connection examples with various sensor types.
For these functions, digital inputs are able to handle signals with frequency up to 500 kHz. Moreover,
the counters values can be automatically stored to nonvolatile (flash) memory in case of power
failure and then loaded back (under development).
Here are a few examples of devices which outputs can be handled by Monarco HAT DIN:
utility meters (electricity, gas, water) with pulse output,
standard quadrature encoders for position/velocity measurement,
gear tooth sensors for position/velocity measurement,
motor controllers with pulse/direction or quadrature position output,
various industrial sensors (temperature, pressure, distance) with frequency output.
There is also a configurable input filter to remove short glitches on digital inputs implemented in
Monarco’s firmware.
