Frequently Asked Questions

• Q: Can I use the 1769‑PA2 to power a controller and I/O together?
• A: Yes, it supplies both 5V and 24V rails. But verify total current draw – max 2.0A @5V and 0.8A @24V.
• Q: How many modules can I connect on one side?
• A: Up to 8 modules per side (16 total) as per power supply distance rating.
• Q: What happens if I exceed the current capacity?
• A: The internal fuse will blow. Replace with Littelfuse 02153.15MXP or Wickmann 19195‑3.15A only.
• Q: Is this power supply suitable for 240V mains?
• A: Yes – input range is 85‑265V AC, 47‑63 Hz, covering 120V and 240V systems worldwide.
• Q: Can I mount this outdoors or in washdown areas?
• A: No – it is open‑style (no enclosure). Must be installed inside a protected panel or cabinet.
