National Instruments NI-9422 C Series Digital Module

The NI-9422 (Part Number: 779522-01) is a C Series Digital Module, which comes with 24 V to 60 V, 8 Digital Input Channels (Sinking/Sourcing Input), Screw Terminal front connectors, and 250 μs maximum update rate. In addition, this module has a Measurement Time which indicates the measure of time over which to quantify and normal numerous times of the information signal.

The counter will go into Dynamic Averaging mode once both the Divisor and the Measurement Time esteems are set. In this mode, the counter at the same time plays out the estimation considering both the Divisor and Measurement Time settings, and returns whichever estimation finishes first.

A quadrature encoder can have up to three channels: A, B, and Z. When channel A leads direct B in a quadrature cycle, the counter augmentations. At the point when channel B drives channel A in a quadrature cycle, the counter decrements. The measure of augmentations and decrements per cycle relies upon the kind of encoding: X1, X2, or X4.

It is possible to take position estimations with the NI 9422 module. The counter measures position utilizing an encoder The NI 9422 returns the current encoder tally esteem when the counter is perused.

The NI-9422 C Series Digital Module has adaptable signal steering highlights. The information signs to the counters can be directed from any of the eight computerized input terminals. By designing the counter properties, the user has the chance to change the signal directing.
