This module combines infrared and ultraviolet sensors in one device to provide robust flame detection. The Fireye 59-546-9 includes an 8-conductor, 9-meter cable assembly with an 8-pin female connector for easy integration. With two flame relays, a fault relay, and two 4-20 mA outputs standard, the 59-546-9 delivers accurate status signals to your control system.\u003c\/p\u003e\u003cp\u003eCommon flame detection failures—such as false trips due to interfering radiation or missed detections from sensor degradation—are addressed by the dual-sensor design of the Fireye 59-546-9. The combination of IR and UV sensing reduces susceptibility to background radiation and ensures consistent operation even with dirty fuels or challenging ambient conditions.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cp\u003eBecause detailed technical parameters were not provided in the product database, please consult the official Fireye documentation or contact PLC Source PRO for complete electrical and environmental data. Based on available information, the Fireye 59-546-9 operates on 24 Vdc input power with a hold time of 20 ms minimum. The relay outputs include two SPDT flame relays and one SPST fault relay. The module supports two 4-20 mA outputs and works with an intrinsically safe wireless handheld commissioning tool.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThe Fireye 59-546-9 is ideal for process heaters, boilers, incinerators, and other combustion systems where flame detection is critical. Its wide operating temperature range (-40°F to +150°F ambient; -40°F to 176°F internal) allows use in outdoor or high-heat locations. The dual-sensor approach solves common problems like flame flicker misreading and sensor blinding. For example, in a refinery heater, the Fireye 59-546-9 can ignore hot refractory glare while detecting a steady flame, reducing nuisance shutdowns.\u003c\/p\u003e\u003ch2\u003eInstallation and Setup\u003c\/h2\u003e\u003cp\u003eMount the Fireye 59-546-9 using a threaded mounting flange (ordered separately). For fiber optic mounts, refer to bulletin CU-117. Purge air requirements: use clean, dry, cool air at 4 SCFM (113 l\/min) through a 3\/8-inch threaded mounting flange or 1-inch Y fitting. At high temperatures or with dirty fuels, increase purge air to 15 SCFM (425 l\/min) to keep the scanner window clean and cool. Connect the 8-conductor cable to the control panel using the provided 8-pin female connector. Ensure the 24 Vdc power supply meets the hold time requirement of 20 ms minimum; Fireye power supply 60-2685 is recommended.\u003c\/p\u003e\u003ch2\u003eMaintenance and Reliability\u003c\/h2\u003e\u003cp\u003eRegularly inspect the scanner window for soot or debris buildup. Clean with a soft, dry cloth or approved solvent. Check purge air flow and pressure to maintain positive pressure against the furnace or windbox. The Fireye 59-546-9 is designed for low maintenance, but periodic testing of flame relays and 4-20 mA outputs ensures system integrity. The module's humidity tolerance (0% to 95% non-condensing) and storage range of -40°F to +185°F support long service life in diverse climates.\u003c\/p\u003e\u003ch2\u003eSelection Guide\u003c\/h2\u003e\u003cp\u003eBefore purchasing the Fireye 59-546-9, verify your system voltage is 24 Vdc and that your mounting flange matches the scanner sight pipe. Order the threaded mounting flange separately if not already available. The 9-meter cable length suits most installation distances; for longer runs, consult technical support. PLC Source PRO (ubest101) stocks this module along with compatible flanges and power supplies.
