Allen-Bradley 1606-XLS480EE Switched Mode Power Supply

The Allen-Bradley 1606-XLS480EE serves as the primary 1606-XLS480EE Switched Mode Power Supply utilized to execute AC-to-DC power conversion and regulated 24 VDC distribution across Bulletin 1606 power supply platforms. The module accepts 200-240 VAC input and delivers up to 20 A output current with an adjustable 24 VDC output for industrial control circuits.

Suffix Breakdown & Model Matrix

The provided documentation identifies 1606-XLS480EE as a fixed catalog number within the Bulletin 1606-XLS series. No official suffix decomposition is specified in the source data.

Hardware Specifications

Firmware Flash Compatibility and Control System Integration

The 1606-XLS480EE is a power conversion device rather than a programmable controller module and therefore does not require application firmware flashing during normal operation. Within Allen-Bradley control architectures, the module supplies regulated 24 VDC power to PLC, communication, and field device circuits. Integration with EtherNet/IP or other deterministic industrial networks occurs through the powered control equipment rather than through the power supply itself.

The DC-OK signaling output can be incorporated into monitoring circuits to provide power status feedback. Proper sizing of the supply relative to downstream load current is required when supporting distributed I/O assemblies and communication infrastructure.

Frequently Asked Questions

Q: Does the 1606-XLS480EE support hot replacement while energized?
A: The supplied specifications do not indicate hot-swap capability. Power isolation and compliance with plant lockout procedures should be followed before replacement.

Q: Can the module accept DC input voltage?
A: No. The provided specifications identify operation from 200-240 VAC input only and explicitly state that DC input voltage is not supported.

Q: What is the purpose of the DC-OK signal?
A: The DC-OK output provides status indication that the output voltage is present and within the module's operating range, allowing connection to supervisory monitoring circuits.

Field Installation Guidelines

• Mount the unit on a suitable DIN rail or panel arrangement according to the installation manual.

• Maintain separation between AC input conductors and 24 VDC output wiring to reduce conducted noise coupling.

• Verify spring-clamp terminal engagement before energizing the circuit.

• Connect protective earth according to local electrical codes and panel design requirements.

• Route signal wiring separately from high-current motor and drive cables where practical.

• Confirm that total connected load current does not exceed the rated 20 A output capability.

• Use appropriately sized conductors based on installation standards and expected load current.
