Overview
The Allen-Bradley 1606-XL120D is a compact switched-mode power supply designed for industrial automation and control panel integration. This 120W unit delivers regulated 24VDC output from standard 120/230VAC line input, making it suitable for retrofit and spare-parts applications in legacy control systems. Though discontinued in April 2018, the 1606-XL120D remains in demand for equipment maintenance and replacement in active installations.
