{"product_id":"allen-bradley-855t-b24tl8-led-stack-light-70mm","title":"Allen-Bradley 855T-B24TL8 LED Stack Light 70mm","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 855T-B24TL8 is a 70 mm control tower stack light module with a yellow lens and black housing, designed for 24 V AC\/DC operation (±10%) in industrial signaling applications. This steady LED module provides continuous illumination with a lamp life rating of up to 100,000 hours and a light output of 900–1800 millicandelas, drawing 29 mA at 24 V. The unit features a 70 mm outer diameter, IP65 and NEMA 4X protection, making it suitable for panel mounting in harsh environments. Construction uses polycarbonate for the surface and vertical-mount pole connection box and magnetic mount housing; it supports a recommended wire size of 0.5 mm² and a terminal torque of 0.8 Nm. Operating temperature is listed at -25 °C with storage down to -40 °C. This specific model was discontinued as of October 1, 2019, with Rockwell Automation recommending the 856T-BT8 as a functional replacement. In practice, the yellow 70 mm stack light serves as a clear status indicator in automated control systems, whether mounted singly or as part of a multi-stack signaling assembly in process or machine control environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657240805678,"sku":null,"price":86.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_d1173571-9d0d-4fdb-9029-7885478f9be8.jpg?v=1769467059","url":"https:\/\/plgautomation.com\/products\/allen-bradley-855t-b24tl8-led-stack-light-70mm","provider":"PLG Automation ","version":"1.0","type":"link"}
