- Provides 24 V DC redundant power capability for compatible ControlLogix chassis
- Uses the documented 1756-CPR2 connection cable in the redundant architecture
- Requires a complete source, cable, chassis-load, and temperature review
1756-PB75R is an Allen-Bradley ControlLogix DC redundant power supply.
It is part of a compatible redundant chassis-power arrangement and must be evaluated with both input sources and the connected ControlLogix load.
Confirm the redundant design, 1756-CPR2 cable, DC source capacity, chassis load, and installed environment before replacement.
Availability, condition, price, and shipping time for 1756-PB75R are confirmed during quotation.

- Match both 24 V DC sources to the approved redundant power design
- Use the documented 1756-CPR2 cable arrangement
- Inspect the complete paired path after a power-loss event
- Calculate the installed ControlLogix chassis load against the documented supply outputs
- Include expansion and module loading in a power-system review
- Use the temperature-conditioned output rating for the installed environment
- Verify DC polarity and input protection before energizing a replacement
- Inspect both source paths rather than only the supply reporting a fault
- Restore control-system power through the approved machine recovery process
- Redundant ControlLogix chassis power architectures
- 24 V DC control systems requiring paired chassis power paths
