Expert Technical FAQ

Q1: Does the 1606-XLS120EA comply with IEC 61508 requirements for use in safety instrumented systems?
A: The 1606-XLS120EA is a high-reliability industrial power supply certified to UL 508 and IEC 60950-1, but it is not independently SIL-rated under IEC 61508. For Safety Instrumented Systems (SIS) requiring a defined Safety Integrity Level, the power supply must be evaluated as part of the overall safety loop architecture. Consult your functional safety engineer to determine if the 1606-XLS120EA’s MTBF data supports your target PFD calculations.

Q2: What firmware or software dependencies exist for the 1606-XLS120EA in a connected Rockwell architecture?
A: As a passive power conversion device, the 1606-XLS120EA operates independently of firmware or software. It requires no configuration within Studio 5000 Logix Designer or FactoryTalk environments. However, when integrated into a system with intelligent power monitoring modules, ensure that the monitoring device’s firmware is current to accurately interpret the PSU’s status signals.

Q3: How does the 1606-XLS120EA perform in high-altitude installations above 2,000 meters?
A: At altitudes exceeding 2,000 meters, reduced air density diminishes convective cooling efficiency. Rockwell Automation recommends applying a derating factor to the maximum output current for installations above this threshold. Consult the official product technical data publication (Pub. 1606-TD008) for altitude derating curves to ensure compliance with thermal management standards at your specific installation elevation.

Q4: Can the 1606-XLS120EA be used in parallel with another unit for N+1 redundancy?
A: Direct paralleling of the 1606-XLS120EA is not supported due to potential current sharing imbalances. For N+1 redundant power architectures — a common requirement in high-availability process control systems — Rockwell Automation recommends pairing individual 1606-XLS units with a dedicated redundancy module (e.g., 1606-XLE series) or implementing diode-OR isolation circuits designed to IEC 60364-5-54 standards.

Q5: What environmental certifications apply to the 1606-XLS120EA for use in corrosive or humid industrial atmospheres?
A: The 1606-XLS120EA is rated for Pollution Degree 2 environments per IEC 60664-1, suitable for typical industrial control panel interiors. For installations in highly corrosive, salt-spray, or condensing humidity environments (Pollution Degree 3 or 4), additional enclosure protection (IP54 or higher per IEC 60529) is required. Verify that the installation enclosure rating aligns with the environmental classification of your facility zone.

Q6: How should the 1606-XLS120EA be decommissioned at end-of-life to meet RoHS and WEEE compliance obligations?
A: The 1606-XLS120EA is manufactured in compliance with RoHS Directive 2011/65/EU, restricting hazardous substances in electrical and electronic equipment. At end-of-life, the unit must be disposed of through a certified WEEE (Waste Electrical and Electronic Equipment) collection and recycling program in accordance with Directive 2012/19/EU. Retain the original declaration of conformity documentation to support waste management audit trails.
