This LED-based light module in the 855E family provides steady illumination with a red lens, enabling continuous status signaling on automation equipment, and it is specified for 24V AC\/DC full voltage operation. The unit features a 52 mm base diameter and 67.7 mm overall height, with wiring compatible for 0.5–1.5 mm² conductors and a current draw around 29 mA; the LED lamp offers approximately 31.4 lumens of illumination and a luminous intensity near 2240 mcd for reliable visibility. The housing is black with a red lens, and the module carries an IP65 rating for protection in demanding environments, with an operating temperature range from -25°C to 50°C. Wiring is facilitated by top-mounted terminals designed for tool-free assembly in a socket-mount configuration, and the 855E stack light can be combined with other 855E\/856T modules to form multi-position towers up to five high. Typical applications include machine signaling, process automation status indication, and operator alert systems on control panels and production lines. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657241166126,"sku":null,"price":43.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2ec6b191-851b-49dd-8cc4-1df3a6143109.jpg?v=1769467064","url":"https:\/\/plgautomation.com\/products\/allen-bradley-855e-24tl4-control-stack-light-module","provider":"PLG Automation ","version":"1.0","type":"link"}
