NI 6624 Specifications Overview Overview and Applications National Instruments 6624 devices are industrial isolated timing interfaces for PCI and PXI/Compact PCI bus systems. You can use the eight 32-bit channel-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, 2-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. NI 6624 devices have been designed from top to bottom to 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 the NI-DAQ software (version 7.2 or higher), which includes NI-DAQmx technology to speed up application development with many helpful features such as the NI DAQ Assistant, automatic code generation, and high-performance multithreaded streaming technology. signal quality and protects computer circuitry. NI 6624 devices provide channel-channel isolation where every channel is physically and electrically separated from the others, which breaks ground loops, improves commonmode 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 can be controlled by external or internal signals. Each counter has one output that can be routed externally or to other counters on the board. 20 MHz and 100 kHz timebases are available on each device for use with each counter/timer. A hardware trigger can be used to start multiple counters simultaneously. 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 to three simultaneous DMA transfers on an NI 6624. You can use interrupts for additional simultaneous buffered transfers. Hardware Connect Sensors Directly with Channel-Channel Isolation Isolation is a form of built-in signal conditioning that provides several advantages. Isolation provides an extended voltage range for direct connection to industrial sensors and actuators. Isolation also improves Industrial, Channel-Channel Isolated, 32-Bit Counter/Timers Figure 1.

NI 6624 Hardware Block Diagram I/O Connector NI 6624 devices each have a 100-pin connector, with a SOURCE, GATE, AUX and OUT signal for each of the counter/timers and two PFI inputs for start triggering. RTSI NI 6624 devices are equipped with the RTSI or PXI trigger bus for multidevice synchronization. Timing signals on an NI 6624 device can be routed to or from other devices in your system to perform advanced timing and synchronization.
