NI PXIE-8135

Working Principle

1. Dual-core x86 industrial processor executes real-time operating system, deterministic control loops and measurement data analysis algorithms
2. PCI Express Gen 2 high-speed PXIe backplane bus provides high-bandwidth low-latency data transfer between controller and all PXIe I/O modules in chassis
3. Integrated multi-channel high-speed memory buffer caches streaming measurement data to avoid data loss during high sampling rate acquisition
4. Front panel peripheral interfaces provide Ethernet, USB, serial port communication to host PC, display and external storage media
5. Hardware watchdog timer monitors CPU operation; triggers automatic controller reboot if software execution stalls or crashes
6. Real-time clock with backup lithium battery maintains system timestamp during chassis power loss

PXIe Chassis Installation Specifications

1. Install module into any vacant 3U PXIe chassis peripheral slot, align backplane edge connector fully seated
2. Maintain minimum 1-slot empty space adjacent to controller for passive heat sink airflow
3. Chassis internal cooling fan must maintain internal ambient temperature below 55°C under full CPU load
4. Route Ethernet/USB communication cables away from high-voltage analog signal cabling to reduce measurement noise
5. Secure front panel cable connectors with locking screw fasteners to resist vibration loosening

Operation & Maintenance Precautions

1. Only use industrial-grade SD storage media for data logging to avoid high-temperature file corruption
2. Disable unused peripheral ports in real-time OS to reduce CPU load and thermal generation
3. Calibrate real-time clock backup lithium battery every 2 years; replace battery if timestamp drift occurs
4. Do not remove module while chassis power is energized to prevent backplane bus damage
5. Avoid continuous 100% CPU load operation above 50°C ambient temperature to extend SSD service life
6. Regularly back up real-time measurement configuration files to external network storage
