Allen-Bradley 855PS-B3OLE322 Power Supply Module

Allen-Bradley 855PS-B3OLE322 is a 22 mm panel-mount signaling device in Rockwell Automation’s 855PS family of panel mount alarms. It provides a visual alert within control cabinets and industrial panels, mounting in a standard 22 mm DIN cutout. The 322 suffix identifies the 22 mm form factor, while the B3OLE322 designation places it within the 855PS LED/optical variants in this family. These alarms are designed for crisp, immediate signaling of fault or status conditions in automation environments, often used alongside other signaling devices to convey machine states to operators and maintenance staff. The 855PS series spans several voltage configurations depending on the exact variant; closely related models in the same catalog show input ranges such as 8–26 V AC/DC, and other listings confirm 12/24 V AC/DC and 24 V AC/DC options across different 22 mm and 30 mm frame sizes. Allen-Bradley manufactures these panel-mount alarms as part of its signaling product lineup, compatible with other Rockwell signaling components used in 22 mm panel installations for industrial signaling.
