A/D refresh rates for SC Controllers
SC Controller A/D refresh rate
SC024-110/112 All: 1.0 ms
SC024-120/122 All: 1.0 ms
SC050-120/122 All: 1.0 ms

Digital/Analog/Frequency (DIN/AIN/FreqIN)
The characteristics of Digital/Analog/Frequency pins are PLUS+1
®
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).
Edge 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.
Maximum frequency The controller may re-boot under some high frequency load conditions above 10 kHz.
