Allen-Bradley 1606-XLRED20-30 Redundancy Module

The Allen-Bradley 1606-XLRED20-30 Dual Redundancy Module provides 24 VDC redundancy for critical automation loads by interconnecting multiple identical power supplies in an N+1 configuration, part of Rockwell’s 1606-XL redundancy family. It accepts a 24 V DC input and delivers a 24 V DC output rated up to 30 A (the model profile specifies a 20–30 A capacity), with the output voltage typically Vin minus about 0.5 V to help maintain stable operation under load sharing. Mounted on a DIN rail in industrial control panels, this module is designed to power PLCs, distributed I/O, drives, and other 24 V loads where uninterrupted operation is essential. The 1606-XLRED20-30 designation denotes the current range it supports, and related models such as 1606-XLRED40 offer higher current capacity for larger installations. As a component of Rockwell Automation’s power-supply redundancy options, it enables reliable uptime in mission-critical applications by providing a resilient path for power when one supply drops out.
