The Linear 2500-1947 is a DC motor drive board for compatible Linear / OSCO automatic gate operators. In a DC operator, the motor drive section is responsible for delivering controlled power to the motor and working with the main control board to manage movement, direction, and protection functions.
This board is commonly tied to UL325-era DC operator platforms and appears in service references for RSL/RSL-D, MSG-D, and SWD style Linear / OSCO equipment. It is also associated with control board assembly reference 2510-245 where a control board and DC motor board are supplied together.
Board fitment is very specific. A similar-looking board can have a different revision, connector layout, safety input requirement, or harness arrangement. Before replacing the board, confirm whether the problem is actually the drive board or whether the operator has a failed motor, weak batteries, blown fuse, damaged charger board, bad limit harness, or binding gate.
This item is commonly associated with the following Linear / OSCO parts, operators, or applications. Confirm the original part number, operator model, voltage, and parts diagram before ordering.

DC drive board replacement should include a full check of power supply, batteries, fuses, charger board, motor condition, limit wiring, and safety inputs. Replacing the board without correcting a short or bad motor can damage the new board.
Board-level diagnosis should be performed by a qualified gate technician. Never bypass photo eyes, sensing edges, or monitored safety inputs to make a gate run.
It is the DC motor drive board that controls motor output in select Linear / OSCO DC gate operators.
Available parts references commonly tie it to RSL/RSL-D, MSG-D, and SWD style Linear / OSCO DC operator applications when the parts diagram matches.
2510-245 is a related control board-with-DC-motor-board assembly reference. Confirm whether your repair needs only 2500-1947 or the larger assembly.
No. UL325 safety requirements must be maintained. Do not bypass monitored safety devices.
Check incoming power, batteries, fuses, charger board, motor wiring, limits, and gate movement so the new board is not damaged by another fault.
