Allen-Bradley Power Supplies

Allen-Bradley Bulletin 1606 control power products are catalogued here. The family holds 46 catalogued part numbers, and every one of them is listed under a single series.

Series in this family

• 1606 Series Power Supplies — 46 catalogued parts. The series represents the Bulletin 1606 platform as a whole.

What the catalogued numbers cover

Most of the catalogue consists of industrial DIN-rail switched-mode power supplies, catalogued under the 1606-XL, 1606-XLB, 1606-XLE, 1606-XLP and 1606-XLS prefixes. The same bulletin also includes redundancy products, a DC-UPS unit and DeviceNet-related power and communication modules, which are listed in the same series.

Ratings and configurations vary by part number, so match the catalogue number exactly from the label of the unit being replaced rather than from output voltage alone. Open the series page for the catalogued list, or send the Bulletin 1606 number with a quote request.

Common Faults

• Capacitor degradation after 7–10 years of service
• Communication errors after firmware drift
• Input/output channel failure from over-voltage events
• Cooling fan failure causing thermal shutdown
• Connector wear in high-vibration installations

Troubleshooting

1. Confirm supply voltage and grounding
2. Inspect diagnostic LEDs and fault codes
3. Verify firmware/configuration matches the application
4. Swap with a known-good unit to isolate the fault
5. Check field wiring and termination

Replacement Options

• Direct OEM replacement (preferred)
• Refurbished OEM unit (cost-effective)
• Compatible cross from the same manufacturer's current catalog
• Equivalent from an alternative manufacturer (engineering review required)

Migration Path

When migrating away from discontinued units, plan for: firmware compatibility, wiring changes, software/configuration migration, spare-parts stock, and field commissioning. Palm Parts Solution can supply both the current generation and stock of the legacy unit while you plan the migration.

Compatibility

Units in this family are compatible with the manufacturer's standard control architecture, communication protocols (where applicable), and accessory ecosystem. Always cross-reference the exact catalog number, firmware revision, and hardware series before installation.
