FAQ
FAQ
Q1. What is the 1769-PB2 used for?
It is a DC power supply that provides backplane power (5V and 24V) for Allen-Bradley 1769 CompactLogix I/O systems.
Q2. What input voltage does it require?
It operates on a 24 VDC input range (20.4–26.4 VDC).
Q3. What is the difference between PB2 and PA2?
PB2 uses DC input power, while PA2 uses AC input power.
Q4. What outputs does the PB2 provide?
It supplies 5 VDC and 24 VDC backplane power for I/O modules.
Q5. Where is the PB2 installed?
It is mounted on the left side of the Compact I/O chassis.
Q6. Can it power the controller directly?
It powers the backplane system; the controller is powered through the same architecture.
Q7. What happens if the input voltage drops?
The system may fault or shut down if voltage goes below operational limits.
Q8. Is it compatible with all 1769 systems?
It is compatible with CompactLogix systems that use 1769 Compact I/O architecture.
