Allen-Bradley 1606-XLDNET4 DeviceNet Power Supply

Configured for power distribution in DeviceNet industrial networks, the Allen-Bradley 1606-XLDNET4 (1606-XLDNET4 Switched Mode Power Supply) provides direct physical execution of 24 VDC power regulation. This unit converts variable AC/DC input voltages into a stable output, specifically rated for 4 A, to maintain consistent power levels across network segments.

Hardware Specifications

DIN-rail Mounting Stability

The 1606-XLDNET4 is engineered for standard DIN-rail mounting, providing mechanical stability in environments subject to vibration. Proper installation on the rail ensures the internal heat sink assembly maintains optimal thermal dissipation characteristics. Users must verify the input voltage switch setting (120 VAC or 230 VAC) prior to application of power to prevent input-stage failure. The modular design enables standard integration into control cabinets, where physical clearance must be maintained to satisfy thermal dissipation requirements and prevent interference with adjacent DIN-rail mounted components.

Frequently Asked Questions

Q: Is this power supply compatible with modern 1606-XLSDNET4 replacement units?

A: The 1606-XLSDNET4 is the designated replacement for the 1606-XLDNET4. While electrical outputs are similar, check the physical mounting dimensions and terminal layout of the new unit to ensure compatibility with existing cabinet spacing and wiring harnesses.

Q: Can this power supply be connected in parallel for redundant power applications?

A: No. Connecting multiple 1606-XLDNET4 units in parallel without the appropriate diode-or redundancy module can lead to circulating currents and potential damage to the internal output stages of the power supplies.

Field Installation Guidelines

• Mounting: Ensure the unit is snapped firmly onto a standard 35 mm DIN-rail. The locking mechanism should be fully engaged to ensure ground continuity through the rail system.
• Input Configuration: Verify the input voltage selector switch position corresponds to the supplied AC voltage. Operating the unit at 230 VAC while switched to 120 VAC will trigger internal protection circuits.
• Wiring: Use appropriately rated wire for the 4 A output load. Ensure terminal screws are tightened to the recommended torque specifications to maintain a low-resistance connection and prevent heat buildup.
• Clearance: Allow a minimum of 50 mm clearance on the top and bottom of the unit to ensure adequate convective airflow, as the 91 W power conversion process generates significant thermal energy under full load.
