It communicates through the Panel Bus and uses a removable electronic module with a separate terminal socket, allowing field wiring to be completed before electronic module installation. The supplied specifications list a 24 VAC power supply and an operating temperature range of 0 to 50 deg C.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\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\u003c\/td\u003e\n\u003ctd\u003eXF823A\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\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003ePanel Bus I\/O Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eHoneywell Excel 800 Panel Bus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003ePanel Bus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e24 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 50 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Type\u003c\/td\u003e\n\u003ctd\u003ePush-in terminals; screw-type terminals also available in the product family\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation\u003c\/td\u003e\n\u003ctd\u003ePluggable electronic module with separate terminal socket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaintenance\u003c\/td\u003e\n\u003ctd\u003eModule exchange without rewiring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApprovals\u003c\/td\u003e\n\u003ctd\u003eCE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandards\u003c\/td\u003e\n\u003ctd\u003eEN 60730-1, EN 60730-2-9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003ePanel Bus Communication and Modular I\/O Design\u003c\/h3\u003e\n\u003cp\u003eThe XF823A belongs to Honeywell's modular Panel Bus I\/O architecture. Its terminal socket can be mounted and wired separately from the removable electronic module, allowing field wiring to be completed before the electronics are installed. Module replacement does not require rewiring the terminal connections.\u003c\/p\u003e\n\u003cp\u003eThe Excel 800 platform supports automatic configuration and commissioning functions for Panel Bus I\/O modules. Compatibility depends on the connected controller supporting Panel Bus communication.\u003c\/p\u003e\n\u003cp\u003eThe broader Honeywell Excel 800 I\/O family supports sensor interfaces including NTC20K, NTC10K, PT1000, NI1000TK5000, PT3000, Balco500, 0\/2-10 V and 0\/4-20 mA. These family-level capabilities should not be interpreted as confirmation that every sensor type is directly supported by the XF823A itself.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the XF823A electronic module be replaced without rewiring the field terminals?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The modular design separates the terminal socket from the removable electronic module, allowing replacement without rewiring the connected field conductors.\u003c\/p\u003e\n\u003cp\u003eQ: Which controller interface is required for the XF823A?\u003c\/p\u003e\n\u003cp\u003eA: The connected controller must support Honeywell Panel Bus communication.
