Description
Product Name: 40847-400 Allen Braley Processor module
Product details:
The Allen-Bradley 40847-400 is a specialized component, typically identified as a Line Filter (or RFI/EMC Filter) used within the PowerFlex series of AC drives and industrial control systems. It is designed to mitigate electromagnetic interference (EMI) and ensure compliance with global EMC standards.
Below is the detailed technical breakdown of this product.
1. Product Description
The Allen-Bradley 40847-400 is an industrial-grade Electromagnetic Compatibility (EMC) Line Filter. In high-frequency switching environments (like those created by VFDs/Inverters), electrical noise can feed back into the power line, disrupting sensitive electronics. This filter acts as a “barrier,” cleaning the power supply to ensure the drive operates reliably without affecting other equipment on the same grid.
2. Technical Parameters
While specific ratings can vary based on the series revision, the standard specifications for the 40847-400 include:
| Parameter | Specification |
| Component Type | EMC/RFI Line Filter |
| Input Voltage | 380V – 480V AC |
| Phase | 3-Phase |
| Current Rating | Generally rated for mid-to-high power drive applications (check specific drive frame size) |
| Frequency | 50/60 Hz |
| Mounting | Typically internal or footprint mounting (depending on the PowerFlex frame) |
| Enclosure Rating | IP00 / Open Type (designed for installation inside a cabinet) |
3. Key Product Advantages
- Noise Suppression: Effectively reduces conducted emissions, preventing interference with sensors, PLC communications, and other digital devices.
- Regulatory Compliance: Essential for meeting CE, UL, and CSA standards regarding electromagnetic compatibility in industrial environments.
- System Longevity: By smoothing out electrical noise, it reduces thermal stress on the drive’s internal components and improves overall system stability.
- Seamless Integration: Specifically engineered by Rockwell Automation to match PowerFlex drive dimensions and electrical profiles, ensuring a “plug-and-play” fit.
4. Installation & Safety Precautions
Warning: Industrial electrical equipment involves high voltages. Installation should only be performed by qualified personnel.
- Proper Grounding: The filter must be securely grounded to the mounting plate (remove paint from contact points) to ensure noise is successfully diverted to the earth.
- Heat Dissipation: These filters generate heat during operation. Ensure adequate airflow within the control cabinet.
- Wiring Distance: Keep the lead length between the filter and the drive as short as possible to prevent the cables from acting as antennas for RFI.
- High Leakage Current: These components often have high earth leakage currents. Ensure a permanent, reliable ground connection is established before applying power.
5. Industrial Applications
The 40847-400 is commonly used in environments where precision and communication integrity are critical:
- Automated Manufacturing: Protecting PLC networks and HMI screens from drive-induced noise.
- HVAC Systems: Used in commercial buildings to prevent interference with sensitive building management systems.
- Water Treatment: Ensuring reliable operation of high-power pumps and telemetry equipment.
- Food & Beverage: Used in bottling and packaging lines where high-speed sensors are sensitive to electrical “jitter.”
