{"product_id":"allen-bradley-856t-btr3-binary-transistor-relay","title":"Allen-Bradley 856T-BTR3 Binary Transistor Relay","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 856T-BTR3 is the transducer sound module for the 70 mm 856T Control Tower stack-light family, designed to provide audible signaling as part of a complete visual indicator. This 24 V AC\/DC device functions as the transducer component within a stack-light assembly to deliver reliable sound output in industrial environments. It supports up to 80 tones, configurable in seven stages via a DIP switch and three input signals, enabling a broad range of audible cues for status, warnings, or alarms. The speaker output is rated at 105 dB(A) at 1 meter, with a maximum of 107 dB(A) at 2,700 Hz, ensuring the signal remains audible over typical manufacturing noise. The 856T-BTR3 is specifically described as a transducer module within the Bulletin 856T lineup and is used in conjunction with other 856T modules and bases to form a configurable signaling tower. Typical applications include machine-status indication, fault alerts, and process alarms on production lines where clear audible signaling complements visual indicators.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657412051246,"sku":null,"price":362.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_935a62fa-f280-47f6-97a3-927f61d2461d.jpg?v=1769468711","url":"https:\/\/plgautomation.com\/products\/allen-bradley-856t-btr3-binary-transistor-relay","provider":"PLG Automation ","version":"1.0","type":"link"}
