What Is the Allen-Bradley 1606-XL60DR?

The Allen-Bradley 1606-XL60DR is a DIN rail mount redundant power supply from the Bulletin 1606-XL series. It delivers a nominal 24 V DC output at 2.5 A, rated 60 W, and includes an integrated decoupling diode for redundant configurations. This module is now discontinued, so buyers should verify current lifecycle status and availability with PetroPartsOnline before ordering.

Engineers searching for a plc power supply module replacement often encounter This unit in legacy panels. Its NEC Class 2 rating and wide AC input range make it a field-proven choice for mission-critical control circuits. However, because Rockwell Automation discontinued this model as of December 31, 2020, with no planned RA replacement, sourcing from a specialist supplier is essential.

Key Features and Technical Specifications

• Input voltage: AC 85...264 V single-phase nominal, supporting global supply networks.

• Output current: 2.5 A nominal, sufficient for many PLC and sensor circuits.
• Rated power: 60 W continuous output.
• Redundancy: Integrated decoupling diode enables true redundant operation.
• NEC Class 2: Meets Class 2 circuit requirements for limited-energy wiring.
• DC OK relay: Provides a status output for remote monitoring.
• Operating temperature: -10...+70 °C, suitable for harsh panel environments.
• Protection rating: IP20 open-frame construction for DIN rail mounting.
• Dimensions (H×W×D): 124 × 49 × 102 mm; weight 0.47 kg.
• Approvals: UL 60950-1, cUL, and CE marked.

The integrated decoupling diode is a standout feature. In redundant systems, it isolates parallel supplies so a single fault cannot drag down the output bus. This design directly supports reliability you can depend on in continuous-process plants.

Why This unit Suits Demanding Oil & Gas Environments

Oil and gas control panels often face temperature swings, vibration, and the need for uninterrupted power. This unit is built for demanding environments, with an operating range of -10...+70 °C and a rugged DIN rail mount. Its 60 W output and 2.5 A current are well matched to PLC racks, transmitters, and small I/O clusters.

Redundant configurations using the integrated decoupling diode help prevent a single supply failure from halting a mission-critical process. For legacy systems where This unit is already installed, keeping a spare on hand reduces downtime risk. Because the model is discontinued, proactive sourcing is a practical reliability measure.

Installation and Setup Guidance

Mount This unit on a standard DIN rail inside a protective enclosure. Connect the single-phase AC input to the 85...264 V terminals, observing local wiring codes. The DC 24 V output feeds the load, while the DC OK relay can be wired to a monitoring system. Ensure the enclosure provides adequate ventilation to stay within the -10...+70 °C operating range.

For redundant operation, use two identical unit units and follow the manufacturer's wiring diagram for parallel connection. The integrated decoupling diode simplifies this setup. Always verify polarity and torque terminals to the manufacturer's specification. If you need application-specific selection guidance, contact PetroPartsOnline for parts suited to your application's requirements.

Compatibility and Integration Notes

This unit has no communication ports or protocols; it is a pure power supply. Therefore, integration is limited to electrical connections. It can feed Allen-Bradley PLC systems and other 24 V DC loads within its 60 W rating. When replacing a failed unit, check that the form factor (124 × 49 × 102 mm) fits the existing DIN rail space.

Because the product is discontinued, direct replacement from Rockwell is not available. PetroPartsOnline can help identify suitable alternatives or locate remaining stock. Always confirm compatibility with your specific panel layout and load requirements.

Frequently Asked Questions

Is This unit still available for purchase?

The Allen-Bradley unit was discontinued as of December 31, 2020. Please verify current lifecycle status and availability with PetroPartsOnline before ordering. We maintain a network for legacy parts sourcing.

What input voltage does This unit accept?

This unit accepts AC 85...264 V single-phase nominal. This wide range covers most industrial supply voltages without adjustment.

Can This unit be used in a redundant configuration?

Yes. This unit includes an integrated decoupling diode, which enables redundant operation when two units are wired in parallel. This design helps maintain power if one supply fails.

What is the operating temperature range of This unit?

The operating temperature range is -10...+70 °C. Ensure the enclosure provides sufficient cooling to remain within this range.

Does This unit have any communication interfaces?

No. This unit has no built-in communication ports or protocols. It functions solely as a power supply.
