Allen-Bradley 1606-XL60D 1606-XL Series Power Supply

The Allen-Bradley 1606-XL60D, also cataloged as the 1606-XL60D Switched-mode DIN-rail Power Supply, operates as a dedicated hardware component for AC to DC power conversion within 1606-XL Series architectures.

Hardware Specifications

Industrial Control & Drive Integration

The 1606-XL60D provides electrical power synchronization across backplane bus communication velocity pathways by delivering regulated 24 V DC to downstream components. In high-density configurations, maintaining voltage stability prevents communication errors within Profinet / EtherNet/IP deterministic networks. The internal regulation loops match the electrical load demands required for physical I/O density scaling, ensuring proper bus delivery across controllers and interface devices without forcing firmware flash compatibility anomalies during transient load switches.

Frequently Asked Questions

Q: How does the internal protection circuitry respond during a sustained short-circuit on the 24 V DC output line?

A: The hardware initiates an automatic short-circuit protection routine that limits output current to prevent thermal breakdown. Once the external fault condition is cleared, the power supply automatically resumes normal 24 V DC output delivery without requiring a manual system reset or power cycle.

Q: What are the specific thermal limits for the 1606-XL60D when operating at full 60 W output power?

A: The module operates at full 60 W capacity from -25 to +60 deg C. When the ambient temperature rises above +60 deg C, linear output current derating rules must be implemented to manage internal thermal heat dissipation profiles and prevent automatic over-temperature shutdown.

Field Installation Guidelines

• Mechanical Mounting and Spacing: Click the module securely onto a standard 35 mm DIN rail. To ensure adequate convection cooling, leave a minimum clearance space of 40 mm above, 20 mm below, and 15 mm horizontally from adjacent hardware components.
• Electrical Input Connections: Wire the AC mains power to the designated L, N, and PE terminals using appropriate gauge wire. Verify that the input voltage falls within the specified 85-264 V AC range before energizing the circuit.
• Grounding Requirements: Connect the PE terminal directly to a low-impedance functional earth ground bar. Ensuring a low-resistance path to ground is critical to maintain internal surge voltage limits and minimize high-frequency noise injection into downstream 24 V DC sensor loops.
