Enhance the versatility of your commercial garage door systems with the LiftMaster AUXCARD Auxiliary Contacts Option Board. This printed circuit board integrates directly with LiftMaster Logic 4 and Logic 5 commercial door operators to provide additional relay contact options for powering external accessories.

Whether you're incorporating lights, alarms, or other auxiliary systems, the LiftMaster AUXCARD offers flexible functionality through both normally open (NO) and normally closed (NC) contacts. It enables on/off control of accessories via relay functions—ideal for facilities requiring complex automation setups.

Please note: when used with NEMA 4 or NEMA 4X rated devices, remote relay control is not supported. An external power source is required for operating any connected accessory, with wiring using #14 AWG copper wire recommended.
