Allen Bradley 1771-P4S /B 120V AC Power Supply Module NEW IN BOX

Allen-Bradley 1771-P4S/B 120V AC Power Supply Module

The Allen-Bradley 1771-P4S/B is a robust 120V AC power supply module designed to deliver reliable 5V DC output at up to 8 Amps, ensuring consistent performance for your PLC-5 system.

Key Features

• Input Voltage: Operates within a range of 97–132 VAC, accommodating standard 120V AC power sources.
• Output Capacity: Provides a steady 5V DC output with a maximum current of 8 Amps, suitable for powering various modules within the 1771 I/O chassis.
• Parallel Operation: Supports parallel configuration with another 1771-P4S module using a 1771-CT paralleling cable, effectively doubling the current capacity to 16 Amps for systems with higher power demands.
• Compact Design: Occupies a single slot within the 1771 I/O chassis, optimizing space utilization without compromising power delivery.
• Protective Features: Equipped with a 1.5 A, 250 V slow-blow fuse to safeguard against overcurrent conditions, enhancing system safety and reliability.

Technical Specifications

• Input Frequency: 47–63 Hz
• Maximum Real Input Power: 59 W
• Maximum Apparent Input Power: 89 VA
• Operating Temperature: 0°C to 60°C (32°F to 140°F)
• Storage Temperature: -40°C to 85°C (-40°F to 185°F)
• Relative Humidity: 5% to 95% non-condensing
• Wire Size: 14 AWG max (single wire only)
• Weight: Approximately 1.85 lbs (0.84 kg)

Compatibility

The 1771-P4S/B is compatible with Allen-Bradley 1771-A1B, -A2B, -A3B, and -A4B Universal I/O chassis, making it a versatile choice for various system configurations.

Installation and Use

Installation is straightforward, with the module fitting directly into the I/O chassis and connecting to the backplane. For systems requiring additional power, two 1771-P4S modules can be connected in parallel using the 1771-CT cable, providing up to 16 Amps of current. Note that this configuration increases current capacity but does not offer redundancy.

Ensure proper wiring connections using the provided Wago 231-205/000-008 connector and adhere to recommended wire sizes to maintain optimal performance and safety.

Conclusion

The Allen-Bradley 1771-P4S/B 120V AC Power Supply Module is a reliable and efficient solution for powering PLC-5 systems, offering flexibility through parallel operation and a compact design that conserves valuable chassis space.
