Allen Bradley 1771-P4S 120V AC Power Supply MDL

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

The Allen-Bradley 1771-P4S is a power supply module designed to deliver reliable 5V DC power to the backplane of 1771 Universal I/O chassis. It is compatible with chassis models 1771-A1B, 1771-A2B, 1771-A3B, and 1771-A4B, making it a versatile choice for various industrial applications.

Key Features

• Input Voltage Range: 97 to 132 V AC at 47 to 63 Hz
• Nominal Input Voltage: 120 V AC
• Output Voltage: 5 V DC
• Maximum Output Current: 8 A
• Module Width: Occupies 1 chassis slot
• Built-in Fuse: 1.5 A, 250 V, slow-blow
• Parallel Operation: Supports paralleling with another 1771-P4S module using a 1771-CT cable to provide up to 16 A of current per chassis

Installation and Compatibility

The 1771-P4S module is designed for easy integration into the 1771 I/O chassis, requiring no additional space outside the chassis. It connects directly to the I/O chassis backplane and features output-power indicators to confirm the delivery of 5 V DC to the backplane. For applications requiring higher current, two 1771-P4S modules can be paralleled to supply up to 16 A per chassis.

• Transformer Load: 148 VA
• Frequency: 47 to 63 Hz
• Weight: Approximately 0.9 kg
• Location: 1771 chassis, 1 slot

Benefits

• Requires no additional space outside the I/O chassis
• Direct connection to the I/O chassis backplane
• Output-power indicators for easy monitoring
• Capability to parallel with another module for increased current supply

The Allen-Bradley 1771-P4S power supply module is a robust and efficient solution for providing consistent 5 V DC power to your 1771 I/O chassis, ensuring reliable operation of your industrial automation systems.
