Linear 2500-1947, Board Dc Motor Drive Ul325
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.

Technician Note
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.
Before Ordering
- Confirm the existing board is marked 2500-1947 or the parts diagram lists it.
- Compare connector layout, board revision, and mounting points.
- Confirm the operator model, such as RSL/RSL-D, MSG-D, or SWD, when applicable.
- Inspect motor leads, batteries, charger, and fuses before installing the board.
- Confirm monitored safety devices are present and working after replacement.
Professional Advisory
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.
Product Q&A
What does the 2500-1947 board control?
It is the DC motor drive board that controls motor output in select Linear / OSCO DC gate operators.
Which operator families is it commonly associated with?
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.
Is 2510-245 the same part?
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.
Can I install it without safety sensors?
No. UL325 safety requirements must be maintained. Do not bypass monitored safety devices.
What should be checked before replacing the board?
Check incoming power, batteries, fuses, charger board, motor wiring, limits, and gate movement so the new board is not damaged by another fault.
