It operates on 10–30 V DC and draws about 200 mA, making it suitable for DC-powered signaling in harsh industrial environments. With 45 selectable tones, it delivers 119 dB(A) at 1 meter (112 dB(A) for the All-Tones configuration), enabling you to tailor alarms to distinct situations while preserving audible clarity around noise-heavy equipment. Ideal for motor-start signals, fault notifications, and general process signaling, this model fits a range of frame sizes and voltage options within the 855H horn lineup to match different panel sizes and wiring schemes.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657423159598,"sku":null,"price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_37b8b374-c1ff-4ba9-afad-cdb45a4784e8.jpg?v=1769468790","url":"https:\/\/plgautomation.com\/products\/allen-bradley-855h-bd30dd-programmable-logic-controller-module","provider":"PLG Automation ","version":"1.0","type":"link"}
