It adds relay-switching capability to a 50 mm stack-light assembly, enabling an external load or circuit to be actuated in response to signals from a PLC or other controller. The module integrates with other 855E stack-light accessories to form compact signaling packages suitable for machine status indication, interlocks, and control of auxiliary devices on production lines. In a typical setup, the 855E family's modular design allows technicians to mix light modules and relay modules to build multi-color indicators with built-in switching functions, reducing panel depth and wiring complexity. The 855E line adheres to applicable industrial signaling standards and is engineered for operation in harsh manufacturing environments, with robust electrical and mechanical interfaces designed to withstand routine panel life. When planning a control tower installation, the 855E-24TC4 should be paired with compatible base and light modules from the same family to ensure proper fit, alignment, and electrical compatibility within the 50 mm stack configuration.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657424470318,"sku":null,"price":193.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_28a60f9c-7a79-4ea4-b3a4-b83677fbdb9c.jpg?v=1769468804","url":"https:\/\/plgautomation.com\/products\/allen-bradley-855e-24tc4-relay-module","provider":"PLG Automation ","version":"1.0","type":"link"}
