Selection Guide

Use the following criteria to determine whether the 1606-XLS120E is the right choice, or to select an appropriate alternative:

• Required Output Power: If load <120W → 1606-XLS120E ✓ | If 120–240W → consider 1606-XLS240E or parallel pair
• Input Supply: Single-phase AC → 1606-XLS120E ✓ | Three-phase → 1606-XLS120E-3
• Temperature Range: Standard (-25 to +70°C) → XLS series ✓ | Extended → XLP series
• Hazardous Area: ATEX Zone 2 required → 1606-XLS120E ✓ | Zone 1 → consult Rockwell
• Redundancy: N+1 required → pair with 1606-XLSRED module
• Budget / Availability: OEM equivalent needed → Phoenix Contact QUINT or PULS QS10 series
• Brand Standardization: Rockwell-only site → stay with 1606-XLS family

Replacement & Compatibility FAQ

Q: Can I replace the 1606-XLS120E with a Phoenix Contact QUINT-PS/1AC/24DC/5?
A: Yes, in most cases. Both are 120W / 24VDC / 5A DIN-rail units. Verify output ripple (<150mVpp) and hold-up time meet your system requirements before substitution.

Q: Is the 1606-XLS120E compatible with three-phase input?
A: No. For three-phase input, use the 1606-XLS120E-3 variant.

Q: Can two 1606-XLS120E units be paralleled for 240W output?
A: Yes, with the 1606-XLSRED redundancy module for proper current sharing and N+1 redundancy.

Q: What is the difference between the XLS and XLP series?
A: The XLP series offers an extended operating temperature range and enhanced diagnostics; the XLS series is the standard slim-line variant optimized for cost and size.

Q: Do you supply original Allen-Bradley units or compatible replacements?
A: We supply both. Please specify your preference when requesting a quotation.
