It operates on 12–24 V AC\/DC (10–26 V range, 50\/60 Hz) and draws a nominal 20 mA at 24 V, with a turn-on leakage current of ≥3 mA. Sound selection is configured externally via the terminal connection, with pulsing tones at a main frequency of 3500 Hz for reliable audible signaling in industrial environments. Fully enclosed with an IP65 rating and NEMA 4X protection, it is built to withstand harsh factory conditions. Mounting is flexible: central mounting for bore holes of 22 mm or 30.5 mm with an appropriate adapter kit, plus a 22.5 mm round mounting hole in the housing, enabling versatile panel integration. The enclosure measures 30 mm in outer diameter and 42 mm in height, weighing about 25 g, with a mounting nut torque of 1.7 Nm. It uses a plug-in terminal block for up to 2.5 mm² (14 AWG) conductors and supports operation down to −25 °C (storage also listed at −25 °C). The 855P-B30SE22 is part of Rockwell Automation’s 855P panel-mount signaling family, with origin in Austria, offering a robust, space-efficient audible alert for control panels, alarms, and process signaling. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657423028526,"sku":null,"price":2174.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8b0fb71f-fe9a-49c9-b192-3a1f83516b60.jpg?v=1769468788","url":"https:\/\/plgautomation.com\/products\/allen-bradley-855p-b30se22-panel-mount-sounder","provider":"PLG Automation ","version":"1.0","type":"link"}
