Allen Bradley 1606-XLBUFFER Buffer Module — Detailed Technical Overview
1. Product Overview
The Allen Bradley 1606-XLBUFFER is a DC buffer module designed to stabilize and maintain power continuity in industrial automation systems. Unlike a standard power supply, this module works alongside a 24V DC power supply to bridge short-term voltage drops, ensuring uninterrupted operation of connected equipment.
It stores energy internally and releases it when input voltage dips occur, helping prevent system shutdowns, PLC resets, or data loss. With a power rating of 480W, it is suitable for medium-load industrial control applications where even brief interruptions cannot be tolerated.
2. Brand Information
Brand: Allen Bradley
This brand is widely used in industrial automation and control systems. It is known for reliable hardware components that integrate well into control architectures such as PLC-based systems and distributed automation platforms.
3. Series Information
Series: 1606 Switched Mode Power Supplies — XL Buffer Module Series
The XL series includes both power supplies and specialty modules such as buffer units. The buffer module is designed as a support device rather than a primary power source.
Key positioning of this series includes:
- Industrial-grade DC power conditioning
- Integration with DIN rail power supplies
- Energy storage for short-term backup
- Maintenance-free capacitor-based buffering
- Designed for high reliability and long service life
This series is typically used where system uptime is critical and power interruptions must be minimized.
