Description
Allen-Bradley 1769-PA2 serves as the primary power source for CompactLogix and Compact I/O installations, supplying stable operating power to controllers and distributed I/O modules. The unit accepts a wide AC input voltage range from 85 to 265V AC, making it suitable for industrial facilities operating with either 120V AC or 220V AC power systems. Its flexible input capability simplifies system integration across different regions and plant environments.

The power supply delivers up to 2.0 A at 5V DC and 0.8 A at 24V DC, supporting the electrical requirements of CompactLogix controllers and associated I/O modules. Power consumption is rated at 100 VA when operating from 120V AC and 130 VA at 240V AC. Even under elevated ambient temperatures up to 60°C, Allen-Bradley 1769-PA2 maintains efficient operation with a power dissipation rating of 8 W.

Installation flexibility is another advantage of Allen-Bradley 1769-PA2. The module can be mounted on either a DIN rail or a control panel using M4 or #8 mounting screws with a recommended torque of 1.16 N•m. For wiring, the unit supports 14 AWG solid copper conductors rated at 90°C or higher, helping ensure reliable electrical connections in demanding industrial environments.

In Compact I/O architectures, Allen-Bradley 1769-PA2 supplies power to modules positioned on either side of the power supply. Up to eight I/O modules may be installed on each side, provided individual module distance ratings are observed. This arrangement offers flexibility when designing control systems while maintaining proper power distribution throughout the assembly.

Allen-Bradley 1769-PA2 is engineered for dependable operation in industrial conditions. The unit provides continuous isolation voltage protection of 265V and withstands vibration levels up to 5 g across a frequency range of 10 to 500 Hz. Operating temperatures range from 0°C to 60°C, while storage temperatures extend from -40°C to +85°C. Combined with a humidity tolerance of 5% to 95% noncondensing, these specifications support long-term performance in manufacturing, processing, and machine control applications.
