Overview
The Allen-Bradley 1606-XLP15B is a compact switched-mode power supply designed for industrial control and automation systems. This unit delivers nominal 12V output (adjustable 12–15V) at up to 1.3A continuous current, making it suitable for small to medium-load PLC modules, safety relays, and auxiliary control circuits. The 1606-XLP15B accepts both AC (100–240V) and DC (85–375V) input, allowing flexible installation in diverse cabinet environments without the need for separate input conditioning.

Compatibility & Replacements
The 1606-XLP15B is part of Rockwell Automation’s industry-standard 1606 Bulletin compact power supply family. It is backward-compatible with legacy Allen-Bradley control systems requiring 12V auxiliary power. The unit integrates seamlessly with CompactLogix, MicroLogix, and SLC-500 architectures when properly fused and current-limited per installation guidelines. For applications requiring higher current capacity, consider the 1606-XLP30B (4.2A, 50W) or 1606-XLP50B (4.5A, 54W) variants. Always verify output current and power requirements before substitution. Installation must follow Rockwell Automation publication 1606-IN021 and site-specific electrical codes.
