{"product_id":"allen-bradley-855t-bpm40-stack-light-base-assembly","title":"Allen-Bradley 855T-BPM40 Stack Light Base Assembly","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 855T-BPM40 Stack Light Base Assembly is the Mounting Base for 70 mm Stack Lights, offering a 70 mm base interface and forming the foundational hardware for Allen-Bradley Control Tower signaling towers. This base is part of the Mounting Base 70 mm Stack Lights family, designed to accept standard 70 mm signaling heads in a vertical stack lighting configuration used to indicate machine state at a distance in industrial environments. The BPM40 designation in the part name identifies the 70 mm base in the 855T line and is associated with configurations that support pole-mounting options in the broader 855T signaling system. Rockwell Automation lists this item as discontinued as of October 1, 2019, with a Functional Replacement in the base\/pole-mount ecosystem, guiding customers toward current 855T bases and compatible pole-mount components for ongoing installations. This base, when paired with appropriate light modules and mounting hardware, enables visible, multi-status signaling—typically used to convey conditions such as running, stopped, fault, or maintenance states—across factory floors, control rooms, and process lines.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657420079406,"sku":null,"price":41.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ba697d02-c0d5-4aae-b0f4-11ac371036ec.jpg?v=1769468743","url":"https:\/\/plgautomation.com\/products\/allen-bradley-855t-bpm40-stack-light-base-assembly","provider":"PLG Automation ","version":"1.0","type":"link"}
