Powered by a high-performance ARM7 processor, the controller executes user-programmed control logic with a fast 100 ms internal logic loop while storing applications and configuration data in nonvolatile Flash memory for reliable operation during power interruptions. The controller operates as either a native BACnet MS\/TP device or as a stand-alone controller, making it suitable for both networked and independent HVAC applications. Compatible with the Alerton Microset® family of intelligent wall sensors, the VLC-444E provides convenient occupant interaction, technician diagnostics, and efficient control of fan coil units, packaged air conditioners, VFDs, dampers, and control valves.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNative BACnet MS\/TP communication: Operates on BACnet networks at speeds up to 115.2 kbps.\u003c\/li\u003e\n\u003cli\u003eFour universal inputs: Auto-sensing 12-bit inputs support thermistors, dry contacts, 0–10 VDC, and 4–20 mA signals.\u003c\/li\u003e\n\u003cli\u003eFour binary outputs: Hot-switched triac outputs rated at 24 VAC, 0.5 A each.\u003c\/li\u003e\n\u003cli\u003eFour analog outputs: 12-bit auto-selectable outputs supporting 0–10 VDC or 4–20 mA control.\u003c\/li\u003e\n\u003cli\u003eHigh-performance ARM7 processor: Provides rapid execution of control programs.\u003c\/li\u003e\n\u003cli\u003eVisualLogic® programming: Fully programmable using Alerton's graphical programming environment.\u003c\/li\u003e\n\u003cli\u003eStand-alone capability: Continues HVAC control independently if network communication is unavailable.\u003c\/li\u003e\n\u003cli\u003eNonvolatile Flash memory: Preserves firmware, applications, and configuration data.\u003c\/li\u003e\n\u003cli\u003eIntelligent wall sensor support: Compatible with the Alerton Microset® family.\u003c\/li\u003e\n\u003cli\u003eIntegrated diagnostics: Dedicated LEDs indicate communication status and binary output operation.\u003c\/li\u003e\n\u003cli\u003eAuxiliary sensor power: Provides 20 VDC, 100 mA output for external 4–20 mA transmitters.\u003c\/li\u003e\n\u003cli\u003eFlexible HVAC applications: Ideal for fan coils, VFDs, packaged air-conditioning units, dampers, and valves.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe VLC-444E delivers the reliability and precision required for intelligent terminal HVAC control, BACnet automation, and energy-efficient commercial building management.\u003c\/p\u003e","brand":"Alerton","offers":[{"title":"Default Title","offer_id":52176005333290,"sku":"VLC-444E","price":645.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l1600_e8962061-c662-4ac9-a21b-6ad2c153d437.webp?v=1785963050","url":"https:\/\/iqelectro.com\/products\/alerton-vlc-444e-bactalk-visuallogic-bacnet-field-controller-with-4-universal-inputs-and-4-analog-outputs","provider":"IQElectro","version":"1.0","type":"link"}
