It provides both battery-backed memory support for SRAM retention and a physical key-switch interface for secure system mode control. This ensures protection of safety-critical application data while enforcing hardware-level operational authorization for system states such as Run, Program, and Force. The module is supplied in 100% brand new original condition to maintain data integrity and operational security within safety instrumented systems.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth\u003eItem\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Number\u003c\/td\u003e\n\u003ctd\u003eFC-BKM-001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunction\u003c\/td\u003e\n\u003ctd\u003eBattery Backup \u0026amp; System Mode Key Switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e24V Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e24V DC (-15% to +30%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e24V Supply Current\u003c\/td\u003e\n\u003ctd\u003eMax 20 mA (typical 7 mA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e5V Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC ±10%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e14V DC to 31V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-5°C to +70°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e176 mm × 35.2 mm × 212 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003e100% Brand New Original\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003ch3\u003eEngineering Advantages\u003c\/h3\u003e\n\u003ch4\u003eMemory Retention Security\u003c\/h4\u003e\n\u003cp\u003eEnsures SRAM data retention during power loss, preserving application logic, configuration parameters, and diagnostic records for rapid system recovery after restart.\u003c\/p\u003e\n\u003ch4\u003ePhysical Mode Enforcement\u003c\/h4\u003e\n\u003cp\u003eProvides hardware-based mode selection via key switch, preventing unauthorized or remote changes to critical system states and supporting compliance with safety integrity requirements.\u003c\/p\u003e\n\u003ch4\u003eFault-Tolerant Power Management\u003c\/h4\u003e\n\u003cp\u003eDesigned with short-circuit protection to prevent damage from wiring faults or accidental grounding, safeguarding both the module and connected backplane circuitry.\u003c\/p\u003e\n\u003ch4\u003eIndustrial-Grade Environmental Resilience\u003c\/h4\u003e\n\u003cp\u003eOperates reliably in harsh environments up to +70°C with wide voltage tolerance, ensuring stable performance under fluctuating industrial power conditions.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003ch4\u003eHow often should the backup battery be replaced?\u003c\/h4\u003e\n\u003cp\u003eTypically every 2–3 years as part of preventive maintenance to ensure reliable memory retention during power loss events.\u003c\/p\u003e\n\u003ch4\u003eWhat system modes are controlled by the key switch?\u003c\/h4\u003e\n\u003cp\u003eCommon modes include Run, Program, and Force, depending on system configuration and Safety Manager software settings.\u003c\/p\u003e\n\u003ch4\u003eIs the FC-BKM-001 compatible with redundant systems?\u003c\/h4\u003e\n\u003cp\u003eYes, it can be used in both redundant and non-redundant Safety Manager configurations as a utility and security module.\u003c\/p\u003e\n\u003ch4\u003eHow is product authenticity ensured?\u003c\/h4\u003e\n\u003cp\u003eAll units are supplied as 100% brand new original Honeywell stock with factory-sealed packaging, original serial numbers, and full OEM documentation for traceability and compliance.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":48951952048380,"sku":"FC-BKM-001","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/FC-BKM-001.jpg?v=1775810973","url":"https:\/\/www.electronicplc.com\/products\/fc-bkm-001-honeywell-battery-and-key-switch-module","provider":"Electronic PLC","version":"1.0","type":"link"}
