Information About 1756-PA72
The 1756-PA72 is part of the ControlLogix power supply family from Allen-Bradley, developed to support various chassis sizes including 1756-A4, A7, A10, A13, and A17. It delivers up to 75W of output power, providing 4A at 3.3VDC, 10A at 5.1VDC, and 2.8A at 24VDC. The supply maintains operation within a temperature range of 0–60 °C and is designed with a hold-up time of 5–6 cycles depending on input voltage, allowing for orderly system shutdown in case of line power fluctuations.
Installed in the leftmost chassis slot, the 1756-PA72 is an open-style module requiring protective enclosure according to NEMA and IEC standards. It features built-in overcurrent protection, reinforced insulation rated at 250V continuous, and tested withstand voltage up to 3500VDC for 60 seconds. With a compact footprint (14.0 × 11.2 × 14.5 cm) and weight of 0.95 kg, this power supply offers reliable operation in both centralized and distributed I/O architectures.
Key Features:
- Design: Standard open-style power supply for ControlLogix chassis.
- Input Voltage: Wide range 85–265V AC, 47–63 Hz.
- Output Ratings: 4A at 3.3VDC, 10A at 5.1VDC, 2.8A at 24VDC, total 75W.
- Hold-up Time: 5–6 cycles depending on input conditions to support orderly shutdown.
- Protection: Built-in overcurrent protection, reinforced insulation tested to 3500VDC.
- Compatibility: Supports ControlLogix chassis types A4, A7, A10, A13, A17 (Series A–C).
- Environment: Operates at 0–60 °C, requires enclosure per NEMA/IEC standards.
- Installation: Mounted in leftmost chassis slot, separate from logic slots.
The 1756-PA72 delivers the reliability and stability required to power ControlLogix systems in demanding industrial automation environments.
