Description Units Minimum Maximum Comment
Allowed voltage at pin Vdc 0 36
Measured resistance Ω 0 10000
Digital/Analog/Frequency(DIN/AIN/FreqIN);Digital/Analog/Frequency/Rheostat(Din/AIN/FreqIN/
Rheo) (All modules except IX012-010, IX024-010)
The characteristics of Digital/Analog/Frequency pins are GUIDE software 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.
General
Description Comment
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.
Expected measurement 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).
xEdge count.
Quadrature count (paired inputs driven from a quadrature encoder).
Pull up/pull down configuration 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.
