Description
The multifunction I/O device produced by National Instruments comes in several part numbers including 780054-01, 780054-07, 780053-04, 780053-01, and 780054-04. This device is designed to offer versatile solutions for data acquisition and control applications.
It supports 16 single-ended or 8 differential analog input channels, providing flexibility in connecting various sensors and signals. The analog-to-digital conversion (ADC) boasts a resolution of 18-bits, ensuring high precision in measurements. For single-channel data acquisition, the device can sample at a rate of up to 625 kS/s, while for multiple channels, the maximum sample rate is 500 kS/s.
Regarding safety, the device offers robust overvoltage protection of ±25 V when powered on and ±15 V when powered off. Additionally, the input current during overvoltage conditions is limited to ±25 mA maximum per AI pin, with an input bias current of ±100 pA.
The multifunction I/O device also includes 2 analog output channels with a digital-to-analog conversion (DAC) resolution of 16-bits. The output update rate reaches up to 2.86 MS/s for a single channel and 2.00 MS/s per channel when both channels are used simultaneously. Lastly, the device ensures timing accuracy within 50 ppm, highlighting its reliability and precision in various applications.
