Allen-Bradley 1606-XLSRED Redundancy Module

The Allen-Bradley 1606-XLSRED is a dual-input redundancy module for DC power in 1606-XLS-based systems, engineered to keep critical loads powered when a primary supply drops out. It accepts two independent 10–60 V DC inputs and delivers up to 480 W of common-output power, enabling true N+1 redundancy for switched-mode power supplies without a separate UPS. The module sits between the two DC sources and the load, employing input isolation (diodes or MOSFET-based OR-ing) so faults on one source cannot pull the output down. Designed to work with the 1606-XLS family, it provides straightforward backup in industrial control panels, packaging lines, and automation cabinets where uninterrupted DC rails are essential. Verified features include dual input channels, a wide input range, a total 480 W output rating, and status indication for each input to help diagnose power faults quickly. By consolidating redundancy into a single housing, the 1606-XLSRED reduces wiring complexity and minimizes downtime risk during a fault condition.
