National Instruments PXI-8145RT

The National Instruments PXI-8145RT is a compact 3U Real-Time Embedded Controller designed for high-performance applications in industrial automation and control. Based on the PCI bus architecture, this controller provides complete PXI functionality through an intuitive interface, making it an ideal choice for users needing reliable control in tight spaces. The PXI-8145RT requires one system slot and one controller expansion slot for installation within a PXI mainframe. It features a Pentium 266 MHz processor capable of executing a single PID loop at a maximum frequency of 6 kHz, ensuring responsive real-time performance. Connectivity options include one RS-232 serial port and one 10/100BaseT Ethernet port, enhancing versatility.

This model utilizes nonvolatile 32 MB CompactFlash memory, which offers robustness against shock and vibration, making it suitable for demanding environments. Additional safety features include a user-programmable timer/counter or watchdog, which initiates a controller reset upon reaching zero in the event of a software fault. The PXI-8145RT also serves as a master/slave controller across the PXI system, optimizing resource management.

For operation, the controller requires the LabVIEW Real-Time Module in conjunction with either the LabVIEW Professional or Full Development System. It includes two user-programmable LEDs on the front panel that can be customized via LabVIEW. The PXI-8145RT boasts a high mean time between failures (MTBF) of 281,262 hours, underscoring its reliability. With dimensions of 1.6 x 5.1 x 8.5 inches and a weight of 0.75 lbs, it is engineered for efficiency. Its operating temperature ranges from 0 to 50 °C, while storage temperatures can reach –20 to 70 °C. Although National Instruments has announced the obsolescence of the PXI-8145RT, Apex Waves will continue to offer this controller for purchase and repair. The product comes with a three-year warranty, and detailed user and maintenance manuals are available for download. For pricing information, please contact a sales representative.
