Configured to respond to input signals generated by external ultraviolet sensors, the solid-state plug-in module converts dynamic flame radiation into a standardized 0.0 to 5.0 Vdc signal path. The hardware interfaces directly with the primary safety control module through a keyed printed circuit board edge connector to enforce flame failure response timing during burner operation.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eR7849A1023\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.15 Kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard 7800 Series Plug-in Form Factor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-40 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePowered via 7800 Series Relay Module edge connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Type\u003c\/td\u003e\n\u003ctd\u003eUltraviolet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlame Failure Response Time\u003c\/td\u003e\n\u003ctd\u003e2.0 sec or 3.0 sec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlame Signal Range\u003c\/td\u003e\n\u003ctd\u003e0.0 to 5.0 Vdc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelf Checking\u003c\/td\u003e\n\u003ctd\u003eNone (Standard)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Sensor Types\u003c\/td\u003e\n\u003ctd\u003eMinipeeper C7027A, C7035A, C7044\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProcess Control \u0026amp; Fieldbus Interface Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe R7849A1023 incorporates dedicated analog signal processing circuitry engineered to isolate low-level ultraviolet sensor inputs from external electromagnetic interference. Featuring front-accessible flame signal test jacks, the module allows non-intrusive measurement of the 0.0 to 5.0 Vdc signal voltage using standard multimeter probes. Onboard channel-to-channel isolation components prevent high-voltage ignition noise from corrupting internal logic lines, maintaining precise timing execution across safety shutdown loops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the physical edge connector prevent improper alignment during insertion into a 7800 Series Relay Module?\u003c\/p\u003e\n\u003cp\u003eA: The printed circuit board edge connector is mechanically keyed to match slot orientation on the host 7800 Series Relay Module, preventing inverted or misaligned insertion.\u003c\/p\u003e\n\u003cp\u003eQ: What measurement devices are compatible with the front panel flame signal test jacks?\u003c\/p\u003e\n\u003cp\u003eA: A standard high-impedance DC voltmeter with a minimum 1 megohm\/volt rating can be connected directly to the test jacks to monitor the 0.0 to 5.0 Vdc signal voltage.\u003c\/p\u003e\n\u003cp\u003eQ: Can the R7849A1023 amplifier be inserted or removed while the host 7800 Series Relay Module is powered?\u003c\/p\u003e\n\u003cp\u003eA: No, line power to the 7800 Series Relay Module must be disconnected before installing or removing the amplifier card to prevent board-level electrical damage.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Isolation:\u003c\/strong\u003e Disconnect all main electrical power supplies feeding the 7800 Series Relay Module before attempting module insertion or extraction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Alignment \u0026amp; Insertion:\u003c\/strong\u003e Align the keyed edge connector of the R7849A1023 with the designated amplifier slot on the relay module base and press firmly until fully seated.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Wire Routing:\u003c\/strong\u003e Route ultraviolet flame sensor leads in dedicated, grounded metal conduit separated from high-voltage ignition transformer cables by at least 100 mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Grounding Practice:\u003c\/strong\u003e Connect sensor cable shields to specified panel ground terminals while keeping shield drains isolated at the sensor end to avoid ground loops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Voltage Check:\u003c\/strong\u003e After burner ignition, insert meter leads into the front test jacks to verify a stable flame signal voltage output between 1.25 and 5.0 Vdc under full load.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":45371269480563,"sku":"R7849A1023","price":410.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/HONEYWELLTK-CCR014_5f57cd52-c192-4b9c-bb11-4f3c9d8550ee.png?v=1787038823","url":"https:\/\/www.dcssupplier.com\/ar\/products\/honeywell-r7849a1023-7800-series-flame-amplifier","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
