It is engineered for use in utility boilers, packaged heating systems, and industrial process furnaces where precise control of purge, ignition sequencing, and flame supervision is required. The module manages pre-purge, post-purge, pilot ignition, and main flame validation logic to ensure stable and safe combustion startup cycles.\u003c\/p\u003e\u003cp\u003eThis controller is designed to reduce operational downtime by enforcing deterministic burner sequencing and fault lockout behavior. It integrates diagnostic feedback, interlock monitoring, and flame signal processing through the 7800 Series architecture, providing high-reliability ignition control under continuous industrial duty conditions.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMicroprocessor-based sequence control for reliable burner ignition.\u003c\/li\u003e\n\u003cli\u003e35 s configurable pre-purge and post-purge cycle control.\u003c\/li\u003e\n\u003cli\u003e2 s pilot flame establishing period.\u003c\/li\u003e\n\u003cli\u003e4 s main flame establishing period.\u003c\/li\u003e\n\u003cli\u003eLockout interlock supervision with automatic fault shutdown.\u003c\/li\u003e\n\u003cli\u003ePurge fan switch verification function.\u003c\/li\u003e\n\u003cli\u003eNonvolatile memory for fault history and sequence retention.\u003c\/li\u003e\n\u003cli\u003eFirst-out fault indication via external display module support.\u003c\/li\u003e\n\u003cli\u003eSupports interchangeable flame amplifier modules.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThe RM7865C1007 is typically deployed in:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIndustrial process furnaces.\u003c\/li\u003e\n\u003cli\u003eUtility and commercial boiler management systems.\u003c\/li\u003e\n\u003cli\u003ePackaged heating systems requiring automated combustion safety.\u003c\/li\u003e\n\u003cli\u003eBurner management systems (BMS) requiring sequence-based ignition control.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eRM7865C1007\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003e7800 Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e120 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eApprox 6 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePre\/Post Purge Time\u003c\/td\u003e\n\u003ctd\u003e35 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePilot Flame Establishing Time\u003c\/td\u003e\n\u003ctd\u003e2 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMain Flame Establishing Time\u003c\/td\u003e\n\u003ctd\u003e4 s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.57 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the system power is disconnected before installing or removing the module from the subbase.\u003c\/li\u003e\n\u003cli\u003eThe module must be installed on a compatible Honeywell 7800 Series subbase.\u003c\/li\u003e\n\u003cli\u003eEnsure proper grounding of the subbase to the chassis to prevent EMI interference.\u003c\/li\u003e\n\u003cli\u003eVerify that the flame amplifier module is correctly seated and compatible with the burner flame sensor type.\u003c\/li\u003e\n\u003cli\u003eRoute high-voltage ignition cables away from low-voltage sensor and communication wiring to prevent signal interference.\u003c\/li\u003e\n\u003cli\u003eEnsure adequate ventilation around the control cabinet to maintain operating temperatures within the 0 to 60 deg C range.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eIs the RM7865C1007 field-programmable?\u003c\/h3\u003e\u003cp\u003eNo, this module operates on fixed safety logic with microprocessor-based sequence control and does not require field-level programming.\u003c\/p\u003e\u003ch3\u003eWhat is required for flame signal processing?\u003c\/h3\u003e\u003cp\u003eThe module requires an interchangeable flame amplifier module (sold separately) to process signals from the flame sensor, depending on your specific burner configuration.\u003c\/p\u003e\u003ch3\u003eHow does the unit handle faults?\u003c\/h3\u003e\u003cp\u003eThe unit features lockout interlock supervision with automatic fault shutdown and supports first-out fault indication when connected to an external display module.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":44673371734104,"sku":"RM7865C1007","price":172.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/wm_1_307db5e6-cedf-42fd-97cc-146efc456cd2.jpg?v=1787943227","url":"https:\/\/www.industriaxplc.com\/ar\/products\/honeywell-rm7865c1007-burner-control-relay-module","provider":"IndustriaX Limited","version":"1.0","type":"link"}
