National Instruments (NI) is extending its offering for industrial applications with PCI data acquisition (DAQ) and motion control devices. The PCI-6230 isolated M series DAQ board features analogue and digital I/O lines with built-in digital isolation for direct connectivity to industrial sensors. Meanwhile, the PCI-7390 position (pulse) command motion controller with built-in isolation offers direct connectivity to popular motion drives, including Yaskawa Sigma II, Mitsubishi MR-J2S and Panasonic Minas A, and provides advanced synchronization capabilities with NI vision and DAQ hardware.

"Isolation circuitry reduces common problems engineers may run into, including ground loops and common-mode voltage limitations," said Dave Lohbeck, NI compliance engineering manager. "The high transient withstand capability of isolated circuit technology guards against voltage spikes, thus helping protect the hardware, engineer and measured data. With the NI product offerings of the PCI-6230 and the PCI-7390, engineers can safely obtain measurements and control actuators or motors in most environments."

The PCI-6230 board features eight 16bit analogue inputs with a 250kS/s sampling rate, four 16-bit analogue outputs with a 500kS/s (max) output rate, six digital inputs and four digital outputs. The board uses digital isolation technology based on chip-scale transformers for increased signal bandwidth and features 1,950Vdc/ 1,400Vrms of channel-to-bus isolation withstand for up to 5s and 60Vdc continuous bank isolation. In addition, the NI-STC 2 system timing controller, NI-PGIA 2 amplifiers and NI-MCal self-calibration circuitry work together to improve performance and accuracy while keeping costs low.

Engineers can use the PCI-6230 board for industrial data acquisition, monitoring and control applications such as reading from encoders, flow meters and proximity sensors, and controlling valves, pumps and relays. The board works with the NI-DAQmx driver software, which promises to reduce application development time with programmatic configuration and automatic code generation. It also integrates with NI's LabVIEW graphical development platform, and engineers can configure it using NI measurement services software on a variety of OSes, including NI LabVIEW Real-Time, Windows, Mac OS X and Linux.

The PCI-7390 controller is a four-axis position (pulse) command motion controller that offers fully programmable motion control for up to four independent or coordinated axes of motion. Equipped with built-in optical isolation, this controller also features dedicated motion I/O for limit and home switches and additional I/O for general-purpose functions, including in-position, inhibit input/drive alarm and servo ready. The PCI-7390 is shipped with the NI-Motion driver that includes motion controller configuration and test utilities; a VI library for LabVIEW; and functions for the NI LabWindows/CVI ANSI C development environment, C and Visual Basic.

NI added that the PCI-7390 controller also offers high-performance features such as position capture triggers and position compare breakpoints for high-speed synchronization of motion with data acquisition and vision hardware in the system.
