At this point six of our cards can process digital inputs. The maximum frequency of input signals, or transitions per second that can be sensed, is the following:
Home Automation Card has 8 optocoupled inputs prepolarized at 5V and can count transitions up to 125Hz.
Industrial Automation Card has 4 optocoupled inputs that can count transitions up to 500Hz
Building Automation Card has 8 dry contacts inputs that can read signals up to 500Hz
The following cards can read both AC and DC signs have a low pass filter at 25 Hz and can count up to 10 transitions per second:
Sixteen Digital Inputs Card, which can read 16 AC/DC signals from 3V to 24V
Four Relays four Inputs Card, which can read 4 AC/DC signals from 3V to 240V
Eight HV Digital Inputs Card, which can read 8 AC/DC signals from 3V to 240V
