Product Description
The Allen-Bradley 1771-P5E is a double-slot, chassis-based power supply module providing 5V DC power to a 1771 chassis. It accepts a 20.5-30V DC input (24V DC nominal), delivering a 5.06V DC output at up to 8A. It features a selectable power loss delay, self-diagnostics with automatic shutdown and restart for over/under voltage and overcurrent conditions, and requires parallel connection only with another 1771-P5E for increased current. Protected by a 5A fuse, it also offers branch circuit protection up to 15A. Operation is indicated by a green LED. It uses 2.5mm2 copper wire and is rated for 0-60C and 5-95% non-condensing humidity without derating. The open-style module is UL, CSA, CE, and C-TICK certified and weighs 2.6 pounds.
Is Your Device Showing These Signs?
The Allen Bradley 1771-P5E power supply commonly experiences issues such as capacitor degradation leading to reduced output voltage and ripple, causing PLC malfunctions. Rectifier diode failures result in complete power loss or intermittent operation. Overheating due to inadequate cooling or component aging damages internal circuitry, triggering fault codes. Connector pin corrosion or damage disrupts power delivery, necessitating replacement or repair. Troubleshooting involves checking output voltage levels, inspecting components for physical damage, and verifying proper wiring connections to ensure stable PLC operation.
