It communicates with the VLX through a twisted-pair multidrop EXP communications bus and can be combined with other EXP modules to extend the controller’s available I\/O. Its 12-bit universal inputs are software configurable for multiple field-device signal types, while the outputs include local Hand-Off-Auto controls for manual override. The module uses a high-speed microprocessor, flash memory, watchdog circuitry, and power-supply monitoring for controller operation and nonvolatile program storage.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eI\/O Configuration: Provides 10 universal inputs, 4 binary outputs, and 8 analog outputs.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eVLX Compatibility: Designed as an I\/O expansion module for Alerton VLX building automation controllers.\u003c\/li\u003e\n\u003cli\u003eUniversal Inputs: Uses 12-bit software-configurable inputs for various field-device signal types.\u003c\/li\u003e\n\u003cli\u003eBinary Outputs: Four binary outputs include local Hand-Off-Auto switching for manual control.\u003c\/li\u003e\n\u003cli\u003eAnalog Outputs: Eight analog outputs provide configurable control signals for connected equipment.\u003c\/li\u003e\n\u003cli\u003eCommunications: Connects to the VLX through a twisted-pair multidrop EXP communications bus.\u003c\/li\u003e\n\u003cli\u003ePower Requirements: Operates from 24 VAC power with a 20 VA minimum requirement.\u003c\/li\u003e\n\u003cli\u003eManual Adjustment: Analog outputs include potentiometers for local adjustment when operated in Hand mode.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe EXP-1048 delivers the reliability and precision required for building automation, HVAC equipment control, and distributed I\/O applications.\u003c\/p\u003e","brand":"Alerton","offers":[{"title":"Default Title","offer_id":52441894977834,"sku":"EXP-1048","price":1899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/ab9f692657dd4396a4afa478ffd60445.jpg?v=1788182001","url":"https:\/\/iqelectro.com\/products\/alerton-exp-1048-hvac-control-system-board-i-o-expansion-module-for-vlx","provider":"IQElectro","version":"1.0","type":"link"}
