  • Model Series: 810 Series (Lam Research Control PCBA Series)
  • Installation Requirements:
    • Install in a standard 6U VME chassis.
    • Ensure proper grounding and ventilation.
    • Torque mounting screws to 0.8 N·m.
  • Usage Notes:
    • Power-off before handling to avoid ESD damage.
    • Operating voltage must be strictly 24 VDC ±5%.
    • Regularly inspect connectors for wear or contamination.
