Description
Response to input below minimum voltage Non-damaging, non-latching; reading saturates to the low limit.
Response to input above maximum voltage Non-damaging, non-latching; reading saturates to the high limit.

DIN/AIN/FreqIN; Din/AIN/FreqIN/Rheo (All models)

The characteristics of Digital/Analog/Frequency (DIN/AIN/FreqIN) pins are PLUS+1
controlled. The input can be digital, analog or frequency.
Inputs can be pulled to 5 Vdc, pulled to ground, pulled to 2.5 Vdc, or no pull-up/pull-down.
Comment
Frequency (Hz)
Period (0.1 µsec)
Channel to channel phase shift (paired inputs . . . ) (0.1 ms).
PWM duty cycle (0.01%)—Duty cycle measurement only valid up to 5 kHz (FreqIN).
Edge count.
Quadrature count (paired inputs driven from a quadrature encoder).
No pull down/ pull up is standard with pull up or pull down programmable; failure modes are detectable.
As with analog input pins, values in the following table assume software compensation for AD converter
offset errors.
