Information About 1756-PB72
The 1756-PB72 is part of the Allen-Bradley ControlLogix family, developed to distribute power across the ControlLogix backplane for controllers and I/O modules. It operates with a 24 VDC supply and provides current outputs of 2 A at 3.3 V, up to 8 A at 5.1 V (derated at higher temperatures), and 2.5 A at 24 V. With reinforced insulation type tested at 3,500 VDC for 60 seconds, it ensures electrical isolation and safety. The module features built-in overcurrent protection, a hold-up time of up to 40 ms, and supports inrush currents of 30 A.
Key Features:
- Input Voltage: Operates from 18–32 VDC with 24 VDC nominal supply.
- Power Output: Provides 95 W input and 75 W usable output at 60 °C for stable system operation.
- Current Capacity: Supplies 2 A at 3.3 V, up to 8 A at 5.1 V, and up to 2.5 A at 24 V.
- Electrical Protection: Built-in overcurrent protection and reinforced insulation tested at 3,500 VDC for 60 seconds.
- Hold-Up Time: Maintains up to 40 ms at 24–32 VDC input, ensuring stable transitions during power dips.
- Environmental Ratings: Operates at 0–60 °C, humidity 5–95%, with 30G operating and 50G non-operating shock.
- Surge & EMI Immunity: ±1 kV line-line, ±2 kV line-earth surge protection, EFT/B immunity up to ±4 kV.
- Chassis Compatibility: Installs on the left side of 1756 ControlLogix chassis (Series A, B, C) for flexible deployment.
The 1756-PB72 delivers the reliability and precision required for powering ControlLogix automation systems in demanding industrial environments.
