It provides five analog inputs and five binary outputs for sensing and actuation, and it is powered from a 24 VAC supply suitable for standard HVAC wiring. As a member of the VLC family, the VLC-550C3 runs Alerton Direct Digital Control (DDC) logic and is programmed with Alerton tools to implement customized control sequences, while communicating on the BACtalk MS\/TP network with other controllers and the building management system. This module serves as a local controller that can operate independently for simple sequences or integrate with a larger BACnet network for centralized monitoring and coordination, helping maintain occupancy comfort, energy efficiency, and equipment performance through precise local control and data reporting.\u003c\/p\u003e\u003c\/div\u003e","brand":"Alerton","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657198436654,"sku":null,"price":435.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f5110c56-e59d-47e8-aea4-b1f1a1f343c3.jpg?v=1769466787","url":"https:\/\/plgautomation.com\/products\/alerton-vlc-550c3-programmable-controller-module","provider":"PLG Automation ","version":"1.0","type":"link"}
