1769-PB4 | Allen‑Bradley CompactLogix DC Power Supply Module
Part Number: 1769-PB4
Manufacturer: Allen‑Bradley / Rockwell Automation
Series: Bulletin 1769 CompactLogix & Compact I/O System
Type: Wide‑Range DC Input Rack Power Supply (4A@5VDC / 2A@24VDC Dual Output)
Lifecycle Status: Active Mature
The 1769-PB4 is a compact dedicated DC power supply engineered for CompactLogix L3x/L3y controllers and 1769-series expansion I/O modules. It accepts wide-tolerance industrial 24VDC input, outputs two independent regulated voltage rails for backplane logic circuits and field auxiliary loads. Built-in multi-layer protection circuits and power status indicator deliver stable power feeding for mid-sized modular automation racks, supporting DIN-rail or panel mounting inside standard industrial control cabinets.
Core Electrical Specifications
- Input Voltage Range: 19.2–31.2 VDC, adapts to common industrial grid voltage drift and line drop
- Max Input Current: 2.0 A, rated apparent power 100 VA @24VDC
- Dual Regulated Output Ratings:
- 5 VDC backplane logic power: 4 A continuous
- 24 VDC auxiliary peripheral power: 2 A continuous
- Expansion Limit: Up to 8 I/O modules connectable on each side, maximum 16 modules in total
- Insulation Grade: Reinforced insulation, 265V continuous withstand rating
- Built-in Protections: Over-voltage, over-current, short-circuit automatic cutoff
- Status Indicator: Front-panel power OK LED for intuitive runtime fault diagnosis
- Recommended Wire Gauge: 22–14 AWG solid wire / 22–16 AWG stranded wire (≥90℃ rating)
Key Product Features
1. Dual Independent Output Rail Design
Separately supplies stable 5VDC for CPU and I/O backplane logic, and independent 24VDC for field sensors, small actuators and auxiliary modules, eliminating extra standalone adapters for compact skid systems.
2. Wide DC Input Adaptability
Broad input voltage tolerance fits factory floors, remote cabinets and mobile industrial equipment with unstable 24V power supply.
3. Flexible Installation & Full Platform Compatibility
Supports standard DIN‑rail and direct panel mounting; fully interoperable with all CompactLogix controllers and 1769 discrete/analog/specialty I/O modules for staged system expansion.
4. Sturdy Industrial Construction
IP20 enclosed housing with passive convection cooling (no fan maintenance required), strong vibration and shock resistance for workshop operating conditions.
5. Mechanical & Environmental Ratings
- Dimensions (H×W×D): 118 mm × 70 mm × 87 mm
- Net Weight: approx. 630 g (1.39 lb)
- Operating Temperature: -40 ℃ ~ +60 ℃
- Storage Temperature: -40 ℃ ~ +85 ℃
- Humidity: 5%–95% RH non‑condensing
- Vibration Resistance: 5g peak (10–500Hz); Shock Resistance:10g peak (11ms)
- Certifications: cULus, CE, qualified for Class I Division 2 hazardous location installation
Typical Industrial Applications
Compact production skid control racks, packaging machinery, small conveyor control systems, food & beverage process equipment, water treatment auxiliary stations, assembly line CompactLogix cabinet power upgrades and legacy 1769 rack spare replacement projects.
Condition Remark Template
✅ New Original: Factory‑sealed genuine Rockwell unit, intact original packaging, official 1‑year manufacturer warranty.
⚙️ Used / Surplus Fully Tested: Pre‑owned unit with full load power output and protection function tested, cleaned and inspected; test report available upon request.
