National Instruments PXI-6624 PXI Counter/Timer Module

The 48 VDC, 8 Channel Isolation PXI-6624 (Part Number: 778975-01) Counter/Timer Module performs a wide assortment of counter/clock tasks, including: event counting, frequency/period estimation, quadrature coder position estimation, pulse width estimation, pulse generation, and generation of pulse series. It has I/O with isolation between 48 VDC channels, eight counters/clocks, 26 digital sources of inputs, and eight digital outputs. The National Instruments PXI-6624 also has 60 V Ch-Ch Isolation, a PXI hybrid bus connector, and 400 kHz source and measure frequency.

Example applications additionally incorporate re-separable pulse generation, flange separation estimations of two signals, continuous event count with buffer, and continuous estimations of the buffer train with buffer. The NI PXI 6624 offers superior industrial strength attributes for a wide assortment of uses, such as car/aviation applications, industrial/motion control, and assembling testing.

With the NI PXI-6624, the user can connect sensors directly with Channel-Channel Isolation. This is a type of inherent signal conditioning that provides several advantages. Isolation provides an extended voltage range to direct connection to industrial sensors and actuators. Isolation also enhances signal quality and secures PC hardware. The PXI-6624 Counter/Timer Module provides channel-channel isolation where each channel is physically and electronically separated from the others, which breaks ground loops, enhances regular mode voltage and noise rejection, and permits the two sections of the circuit to be at various voltage levels. Numerous industrial applications require isolation to protect the electronics from transient voltage spikes and give more noteworthy common-mode noise rejection in electrically noisy environments containing apparatus and inductive loads.
