The LiftMaster K1D8387-1CC gate operator expansion board from North Shore Commercial Door is compatible with LiftMaster DC (direct current) swing gate and slide gate operators made after 2016. These operators, such as the LiftMaster SL300UL slide gate operator, must have the letter "U" in the model number.
An expansion board, sometimes called a daughter board, adds more programming functions to your LiftMaster gate opener. With an expansion board, you can add external loops and other inputs. The K1D8387-1CC LiftMaster expansion board is backwards-compatible with pre-2016 LiftMaster gate operators if UL325-compliant entrapment protection systems and photo eye safety sensors are added.
