FAQ
FAQ
Q1. What is the 1769-PA2 used for?
It is the main AC power supply that provides 5V and 24V backplane power for Allen-Bradley 1769 CompactLogix I/O systems.
Q2. Does the 1769-PA2 power the CPU directly?
No, it powers the Compact I/O backplane, and the controller draws power through the system architecture.
Q3. What input voltage does it require?
It supports a wide input range of 85–265 VAC, making it compatible with 120V and 240V systems.
Q4. How much output current does it provide?
It provides 2.0 A at 5V DC and 0.8 A at 24V DC for the backplane.
Q5. Where is it installed in the system?
It is installed on the left side of the 1769 I/O rack.
Q6. What happens if the power supply fails?
All connected I/O modules lose backplane power, causing system shutdown or fault condition.
Q7. Can multiple power supplies be used in one system?
Yes, large systems may use multiple PA2 units to support segmented I/O banks.
Q8. Is it compatible with all 1769 controllers?
It is compatible with CompactLogix 1769-L3x family systems that use 1769 Compact I/O architecture.
