Frequency Counter Inputs
Digital signals are updated to the display at a rate of 10 times per second (10 Hz). Digital inputs are low
when the signal is
≤
2 Vdc or the resistance to ground is
≤
375
Ω
, and high when the signal is > 3.5 Vdc
or the resistance to ground is > 100 k
Ω
. Digital inputs can also be configured as discrete inputs.
