High-precision audio and vibration measurements
For the first time on the PXI platform, engineers can make precision audio and vibration measurements with the National Instruments NI4472.
Modules condition a range of sensor signals
National Instruments has released new Signal Conditioning Component modules for frequency to voltage conversion, integrated circuit piezoelectric accelerometers and RTDs.
The USB-6509 delivers, to a portable USB form factor, an industrial feature set of four high-reliability features for industrial or harsh applications previously available only in PCI and PXI systems.
The industrial feature set includes programmable power-up states, digital I/O watchdog timers, change detection and programmable input filters.
With programmable power-up states, engineers can predefine the state in which the USB-6509 device powers up, ensuring consistent, reliable operation when connected to industrial actuators such as pumps, valves, motors or relays.
Digital I/O watchdog timers can detect a variety of fault conditions such as a computer crash and automatically respond by setting the outputs to a user-defined safe state.
With change detection, the device automatically triggers an application to perform a read operation after a digital line changes state.
Also, engineers can eliminate unintended glitches and spikes in input data and avoid false readings caused by noise with programmable input filters.
The 96-channel device is compatible with TTL, CMOS and 5V digital logic levels and each port of eight lines is individually configurable for input or output.
The USB-6509 can drive external digital devices such as solid-state relays with current up to 24mA per line, and pull-up and pull-down resistors included on the device stabilise the bus potential during a nonaccess state.
The bus-powered device can source up to 215mA total across all digital output lines.
An optional 12V DC power supply is available for additional sourcing current.
The USB-6509 works with NI-DAQmx driver software, which features an easy-to-use and intuitive interface for programming.
The device is also compatible with NI LabView, NI LabWindows/CVI, ANSI C/C++, Visual Basic.NET, C# and Visual Basic 6.0. Request a free brochure from National Instruments ...
