Allen-Bradley 1336-BDB-SP29A Main Drive Board – 1336 PLUS AC Drive Series
When the main drive board inside an Allen-Bradley 1336 PLUS AC drive fails, the impact on the production floor is immediate and severe. Variable-frequency motor control is lost in an instant — conveyor systems stop, pump stations lose flow regulation, compressor drives trip offline, and process lines dependent on precise speed control go into uncontrolled shutdown. Without a verified replacement board on hand, maintenance teams face extended downtime, emergency sourcing delays, and the cascading costs of halted production. The Allen-Bradley 1336-BDB-SP29A (P/N 74101-169-53) Main Drive Board is the core power-switching intelligence of the 1336 PLUS drive, and restoring operation depends entirely on sourcing the correct, compatible replacement without delay.
The 1336 PLUS series — Rockwell Automation’s widely deployed general-purpose AC drive platform — has accumulated a massive global installed base across manufacturing, infrastructure, and process industries. Within this family, the 1336-BDB-SP29A serves as the main drive board (MDB), responsible for gate-drive signal generation, IGBT switching control, DC bus interface, and power stage protection logic. The suffix SP29A identifies a specific hardware and firmware revision that must be matched to the corresponding power structure and control board assembly. This board is an essential MRO spare for any facility maintaining 1336 PLUS drives in continuous operation.

Frequently Asked Questions
Q: Is the 1336-BDB-SP29A compatible with all 1336 PLUS drive frames?
A: The SP29A revision is specific to certain 1336 PLUS frame configurations. Compatibility depends on your drive’s full catalog number, frame size, and existing firmware revision. Please provide your complete drive catalog number when submitting an inquiry so we can confirm compatibility before shipment.
Q: What is the difference between a new, surplus, and refurbished board?
A: New boards are unused OEM stock. Surplus boards are new-in-box but may have been stored for extended periods. Refurbished boards have been inspected, repaired if necessary, and tested to OEM specifications. All conditions are clearly disclosed at the time of quotation.
Q: Can you ship the 1336-BDB-SP29A internationally?
A: Yes. Konmask.com ships globally via DHL, FedEx, and UPS with full export documentation. Lead times and shipping costs are confirmed at the quotation stage.
Q: Do you offer a warranty on this drive board?
A: Warranty terms vary by condition and sourcing channel. Tested-good and refurbished units typically carry a 90-day functional warranty. Details are specified in the proforma invoice.
Q: How can I tell if my 1336 PLUS drive needs a new main drive board?
A: Common indicators include persistent power stage fault codes that do not clear after power cycling, IGBT switching errors, DC bus voltage irregularities, or visible damage to the drive board PCB. Our technical team can assist with remote fault diagnosis and part identification.
