Allen-Bradley 1606-XLBUFFER is a DC buffer module that provides up to 20 A of buffered output at 23–27.8 V DC (up to 480 W) to support 24 V loads in control-system applications. It accepts 24–28.8 V DC input and is designed as a supplementary device for regulated DC 24 V power supplies. Typical use cases include maintaining a stable DC bus for PLCs and automation devices during brief input disturbances.
