Operating from 24V AC\/DC (±10%), it draws about 45 mA and fits within a 69.5 mm footprint with a black housing, offering IP54 protection and NEMA 12 compatibility for use in industrial environments. This Type 12, single-tone\/single-circuit module can produce either continuous or pulsing tones, with tone selection modified by a DIP switch and output levels of 97 dB or 85 dB at 1 meter, ensuring audible signaling across noisy facilities. The component is designed for 24V AC\/DC full-voltage operation and is part of Allen-Bradley’s 855T family of sound modules, intended to be mounted in stack-light configurations to convey status, warnings, or fault indications. Typical applications include manufacturing automation lines, packaging conveyors, and process control environments where reliable audible cues help operators and maintenance staff respond quickly. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657420833070,"sku":null,"price":130.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f15b54e4-5f52-4058-bf90-6ac9bd286e93.jpg?v=1769468756","url":"https:\/\/plgautomation.com\/products\/allen-bradley-855t-b24sa2-single-tone-sound-module","provider":"PLG Automation ","version":"1.0","type":"link"}
