It operates on 10-30 VDC and delivers 119 dB of sound with 45 selectable tones, enabling distinct alarms or status signals in noisy facilities. Housed in gray with a standard base, it is designed for surface mounting and supports back-feed or conduit-feed wiring for flexible installation. This model is part of Rockwell Automation's 855H signaling family and is suitable for panel- or machine-mounted signaling to alert operators to faults, safety interlocks, or process alarms across manufacturing lines, conveyors, and control panels. The 10-30 VDC input and multi-tone capability support differentiation of conditions within a single unit, and the 3-stage signaling allows varying alarm levels across tones. Its compact form factor and robust construction suit demanding industrial environments, making it a straightforward addition to an existing control circuit where an audible alert is required.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659284676910,"sku":null,"price":258.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c438c1be-b9f0-4cd8-9eb0-8ab757afc12d.jpg?v=1769529016","url":"https:\/\/plgautomation.com\/products\/allen-bradley-855h-bd30dd-industrial-alarm-horn","provider":"PLG Automation ","version":"1.0","type":"link"}
