It integrates a digital display, supports continuous recording of multiple process variables, and outputs analog signals for connected controllers. Optimized for industrial and laboratory environments (through blast furnaces, cold rooms, etc.), it can support one or two controller loops. Despite its discontinued status, used and refurbished units are still sourced through specialty distributors with warranties and repair support.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMultiple Process Variable Recording: Logs up to four variables simultaneously on the same timeline.\u003c\/li\u003e\n\u003cli\u003eHybrid Analog\/Digital Output: Combines analog fiber-tip pen traces with precise digital readings.\u003c\/li\u003e\n\u003cli\u003eDigital Display: Shows current process variable values in engineering units.\u003c\/li\u003e\n\u003cli\u003eConfigurable Input Ranges: Compatible with various sensors and transmitters.\u003c\/li\u003e\n\u003cli\u003eOptional Loop Control: Offers one or two digital controllers to operate valves, dampers, etc.\u003c\/li\u003e\n\u003cli\u003eField Repair Support: Refurbished units and component-level repair available.\u003c\/li\u003e\n\u003cli\u003eCompact and Lightweight: Approximately 0.22 lb (0.1 kg), easy to install.\u003c\/li\u003e\n\u003cli\u003eOEM Discontinuation: No longer produced by Honeywell, available via third-party suppliers.\u003c\/li\u003e\n\u003cli\u003eWarranty Options: Available with up to 2-year support through refurbishers.\u003c\/li\u003e\n\u003cli\u003eIndustrial Reliability: Designed for continuous operation in industrial settings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 51309355-001 delivers reliable multi-variable recording and control in industrial chart recorder systems.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":49105308778752,"sku":"51309355-001","price":3747.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/Honeywell_51309355_001_View1_2019103164151.jpg?v=1785544636","url":"https:\/\/alotechparts.com\/products\/51309355-001-honeywell-processor-main-board-dr4500-chart","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
