6-Channel C Series VR/Hall Interface Module—The NI‑9760 features six differential input channels that are individually configurable as variable reluctance (VR) or Hall effect sensor inputs. Each channel features an external digital output, which passes out the conditioned, digital version of the VR/Hall input signal. The VR circuits use adaptive noise rejection during continuous incoming VR pulses. You can configure fixed arming thresholds using DAC setpoints. The Hall effect circuits read a wide variety of single-ended or differential digital signals from Hall effect and proximity sensors or any digital signal source. You can also configure the logic threshold with DAC setpoints. Each Hall effect channel includes a programmable pull-up resistor for accommodating sensors with open-collector outputs.
