{"product_id":"liftmaster-auxrel","title":"LiftMaster AUXREL Auxiliary Relay Board — MAXUM Commercial Operators","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster AUXREL adds configurable auxiliary relay outputs to supported MAXUM commercial door operators. It can provide switching signals for appropriate external devices, such as a low-voltage indicator or audible alert, according to the selected relay function. The manufacturer documents two relays with normally open and normally closed contacts and restricts the external circuits to Class 2 low-voltage sources within the stated ratings. Match the operator, accessory connection and intended load before choosing this board for an installation.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported MAXUM JDC \/ JHDC \/ TDC arrangements\u003c\/td\u003e\n\u003ctd\u003eVerify the exact model manual and accessory connection.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal lights, bells or horns\u003c\/td\u003e\n\u003ctd\u003eLoad and power source must meet the documented contact and accessory-power limits.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLPEXP loop expansion board\u003c\/td\u003e\n\u003ctd\u003eA separate accessory; the manual describes independent or combined installation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOlder Logic-series accessory sockets\u003c\/td\u003e\n\u003ctd\u003eDo not assume compatibility from the relay function alone.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMains-voltage loads\u003c\/td\u003e\n\u003ctd\u003eNot permitted directly on the documented Class 2 relay connections.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eSelect the Relay Function and Electrical Load Together\u003c\/h2\u003e\u003cp\u003eA relay can report an operating condition without supplying power to the external device.
