NEW ARRIVAL: Allen-Bradley 1769-PB4 CompactLogix Power Supply Now Available
Model Description
We are pleased to announce the immediate availability of the Allen-Bradley 1769-PB4 CompactLogix power-supply module, a rugged 24 V DC unit engineered to feed both 5 V backplane logic and 24 V field power to 1769 Compact I/O racks. Accepting 19.2 – 31.2 V DC input, the module delivers 4 A @ 5 V and 2 A @ 24 V, enabling up to eight I/O modules to be placed on each side (16 total) without additional supplies. The 118 × 70 × 87 mm footprint clips onto standard 35 mm DIN-rail or panel-mounts in seconds, while finger-safe IP20 screw terminals accept 22 – 14 AWG solid or 22 – 16 AWG stranded copper. Weighing only 0.58 kg and consuming 100 VA, the PB4 is ideal for machine skids, packaging lines and distributed I/O islands where space, weight and reliability are critical .
Key Features
1769-PB4 provides reinforced 75 V (continuous) isolation between input and logic, routine-tested at 1 697 V DC for 1 s, ensuring safe operation in mixed-voltage panels. An integrated 6.3 A fuse (Wickmann 19193 or Littelfuse 021706.3MXP) protects the primary feed, while 30 A inrush capability handles large start-up loads without nuisance trips. Power dissipation is a low 14.5 W @ 60 °C, so side-by-side mounting is possible without derating. Certified to CE, cULus, ABS, GL, ATEX and IECEx, the supply is ready for factory, marine or Zone 2 applications. A green “POWER” LED gives instant status, and the non-repairable design guarantees long, maintenance-free service life—20 g shock and 2 g vibration ratings keep processes running even on presses, cranes or offshore platforms .

Rockwell Automation offers drop-in alternatives for different load profiles. 1769-PB2 halves the current (2 A @ 5 V, 1 A @ 24 V) for smaller racks, while 1769-PA4 accepts 85 – 265 V AC and delivers 5 A @ 5 V for line-powered systems. 1769-PB4K ships factory-sealed for OEMs needing a tamper-evident version. All units share identical 118 mm height, 35 mm DIN-rail position and wire-way spacing, allowing panel builders to standardise cut-outs and upgrade capacity without rewiring. Common accessories—such as 1769-RTB18 removable terminal blocks or 1769-ECR end-caps—snap on in seconds, further simplifying inventory and assembly .
