Oiltech Controls’s Insight

• ▪ The 1769‑PA4 is a workhorse for CompactLogix systems. Its selectable input range makes it versatile for global installations.
• ▪ We recommend verifying the power supply distance rating – it is critical for stable system operation.
• ▪ For systems with many analog or high‑power output modules, consider adding a second power supply to share the load.
• ▪ The replaceable fuse is a practical field‑service feature – keep a spare on hand.

Professional FAQ – 5 Expert Q&A

• Q1: How do I choose between 85‑265V and 170‑265V input?
  Set the switch to match your local mains. For 120V systems, use the 85‑265V range. For 240V systems, the 170‑265V range provides better inrush protection. Always check before energizing.
• Q2: Can I mount this power supply on a DIN rail with other 1769 modules?
  Yes. It is designed for DIN‑rail mounting and integrates directly with CompactLogix assemblies. Use the upper/lower latches for secure attachment.
• Q3: What is the maximum number of I/O modules I can connect?
  Up to 8 modules on each side (total 16) provided the total current draw does not exceed 4.0 A @5V or 2.0 A @24V. Always calculate the load budget.
• Q4: The fuse blew – what replacement part do I need?
  Use Littelfuse 02153.15MXP or Wickmann 19195‑3.15A. These are standard 3.15 A, 250 V fuses. Keep spares for quick field replacement.
• Q5: Is this power supply compatible with 1769‑L16 or L18 controllers?
  No. The 1769‑PA4 is designed for the 1769‑L3x series. For CompactLogix 5370 (L1/L2), use the 1769‑PA2 or 1769‑PB2. Check your processor’s power requirements.
