You can use the eight 32-bit channel-to-channel optically isolated counter/timers of an NI 6624 device to perform a wide variety of buffered measurements or other counter/timer tasks, including position or quadrature encoder measurement, edge counting, period measurement, pulse-width measurement, frequency measurement, semiperiod measurement, two-edge separation measurement, pulse-width-modulation (PWM) generation, pulse, and pulse-train generation. NI 6624 devices offer superior features and high value for automotive test, industrial monitoring, and manufacturing test applications such as factory automation, embedded machine control, and production line verification. They incorporate the latest hardware technologies and provide innovative features for applications requiring ease of use, high reliability, and performance. NI 6624 devices take advantage of NI-DAQmx software (Version 7.2 or later), which speeds up application development with many helpful features such as the NI DAQ Assistant, automatic code generation, and high-performance multithreaded streaming technology. Connect Sensors Directly with Channel-to-Channel Isolation Isolation is a form of built-in signal conditioning that provides several advantages including an extended voltage range for direct connection to industrial sensors and actuators. It also improves signal quality and protects computer circuitry. NI 6624 devices offer channel-to-channel isolation, where every channel is physically and electrically separated from the others, which breaks ground loops, improves common-mode voltage and noise rejection, and permits the two parts of the circuit to be at different voltage levels. Many industrial applications require isolation to protect the electronics from transient voltage spikes and provide greater common-mode noise rejection in electrically noisy environments containing machinery and inductive loads. Counter/Timers Based on NI-TIO ASIC NI 6624 devices are equipped with the NI-TIO ASIC, a National Instruments counter and digital I/O ASIC for advanced timing and counting applications. Each NI 6624 features two NI-TIO ASICs to provide a total of eight counter/timers. Each counter has a gate, auxiliary, and source input, which you can control with external or internal signals. Each

counter also has one output that you can route externally or to other counters on the device. 20 MHz and 100 kHz timebases are available on each device for use with each counter/timer. You can use a hardware trigger to start multiple counters simultaneously. Figure 1. NI 6624 Hardware Block Diagram Buffered Measurements NI 6624 devices use the National Instruments MITE bus interface controller to implement bus-master DMA transfers. As a result, you can perform high-speed, continuous operations such as buffered position encoder measurement and buffered period measurement. You can perform up...
