National Instruments PXI-8145RT PXI Real-Time Embedded Controller

Based on the PCI bus, the National Instruments PXI-8145RT (Part Number: 778201-01) is a 3U Real-Time Embedded Controller. Featured with complete PXI functionality through interactive utilities, this model is a simple to utilize, high-performance platform for controlling PCI systems. The device requires 1 system slot and 1 controller expansion slot to operate. This PXI Real-Time Embedded Controller is a custom computer that can be installed in the system controller slot of the user’s PXI mainframe. The NI PXI-8145RT is well-suited for affordable, real-time applications where minimal space is available.

The National Instruments PXI 8145RT features one RS-232 serial port, one 10/100BaseT Ethernet port, and a Pentium 266 MHz processor which can run one PID loop at 6 kHz maximum. The PXI-8145RT can ensure high shock and vibration since it utilizes nonvolatile CompactFlash memory. The CompactFlash memory size is 32 MB. This PXI Controller has a user-programmable timer/counter or watchdog with an ability to countdown from a value specified by the user. Users can reset the watchdog controller through a backplane trigger line. To provide maximum safety, the watchdog counter is programmed to initiate a controller reset when it reaches zero because of a software crash. When used in the system slot, the NI PXI 8145RT provides all slots in the PXI system with master/slave capabilities.

This controller is run using the NI-DAQ driver software, and is compatible with several types of software such as NI-VISA. However the required software is the LabVIEW Real-Time Module and the LabVIEW Professional or Full Development System. In addition to other LEDs, the front panel of the PXI 8145RT has two user programmable LEDs, which can be programmed via LabVIEW. The NI PXI-8145RT has a high MTBF (mean time between failures) of 281,262 h. The device weighs 0.75 lbs., and measures 1.6 x 5.1 x 8.5 in. in physical dimensions. It has a recommended operating temperature range of 0 to 50 °C, and a storage temperature range of –20 to 70 °C.

PXI-8145RT Obsolete Status has been announced by National Instruments, but this controller will still be available for purchase and repairs by Apex Waves.
