Restore full operation to your LiftMaster Mega Arm barrier gate with this genuine OEM replacement circuit board model MA001, engineered specifically for the MATDCBB series of heavy-duty DC barrier gate operators.

This is a genuine OEM logic control replacement board Ma001 designed for use with Mega Arm and Mega Arm Tower DC barrier gate operators, restoring logic functionality and ensuring reliable performance in high-speed, commercial-grade gate automation systems.

Compatible With: This replacement control board Ma001 is compatible with the MASDCBB (Mega Arm Sprint DC Barrier Gate Operator), MATDCBB (Mega Arm Tower DC Barrier Gate Operator), and the MAS Mega Sprint High-Speed DC Barrier Operator.

Engineered for High-Cycle Commercial Performance: The MATDCBB series supports up to 6,000 cycles per day at an operator speed of 2.5 seconds to open or close, making it the control board of choice for parking structures, toll lanes, gated communities, and industrial facilities.
