Allen-Bradley 1336-PB-SP2C Circuit Board – 1336 PLUS AC Variable Frequency Drive Series
When a critical circuit board fails inside an Allen-Bradley 1336 PLUS AC drive, the consequences ripple instantly across the production floor. Conveyor lines halt, pump stations lose control, and HVAC systems go offline — every minute of unplanned downtime translates directly into lost output and escalating maintenance costs. In facilities where continuous operation is non-negotiable, having the right replacement board available is not a luxury; it is an operational imperative.
The Allen-Bradley 1336-PB-SP2C (alternate part number 74101-502-57) is the OEM power base circuit board designed specifically for the 1336 PLUS series of AC variable frequency drives. As one of Rockwell Automation’s most widely deployed drive platforms across global manufacturing, water treatment, and material handling industries, the 1336 PLUS remains a backbone component in thousands of installed systems worldwide. This board governs core power conversion and gate-drive functions, making it a non-substitutable element in drive restoration and repair workflows.

- Cost-Effective Repair Path: Board-level replacement is significantly more economical than full drive replacement, preserving existing panel wiring and programming.
- Tested Before Shipment: Each unit undergoes functional verification prior to dispatch to minimize the risk of DOA components reaching your facility.
Industry & Equipment Applications
- Manufacturing & Assembly: Conveyor systems, robotic work cells, and CNC machine tool spindle drives.
- Water & Wastewater Treatment: Pump station VFD panels controlling flow rates and pressure.
- HVAC & Building Automation: Air handling unit fan drives and chiller compressor control.
- Oil & Gas: Wellhead pump drives and pipeline booster stations.
- Material Handling: Hoist, crane, and elevator drive systems requiring precise speed regulation.
- Food & Beverage Processing: Mixer, extruder, and packaging line motor control.
System Integration & Compatible Parts
The 1336-PB-SP2C is designed to integrate within the broader 1336 PLUS drive architecture. When performing a board-level repair, the following related components are commonly evaluated simultaneously:
- 1336-L6 / 1336-L10 — Control boards for the 1336 PLUS series
- 1336-MOD-L6 — Optional I/O expansion modules
- 1336-PB-SP1 / SP3 — Alternative power base boards for different frame sizes
- 1336-BRF — Dynamic braking resistor assemblies
- 1336-PLUS-SP1 — Spare parts kits for preventive maintenance programs
Always cross-reference your drive’s full catalog number and firmware version with Rockwell Automation’s compatibility matrix before installation.

Frequently Asked Questions
- Q: Is the 1336-PB-SP2C compatible with all 1336 PLUS drive frame sizes?
- A: No. Power base boards are frame-size specific. Please provide your complete drive catalog number (e.g., 1336F-BRF30-AN-EN) so we can confirm compatibility before shipment.
- Q: What is the difference between part numbers 1336-PB-SP2C and 74101-502-57?
- A: These are the same physical board. 1336-PB-SP2C is the Rockwell Automation catalog/spare part number, while 74101-502-57 is the PCB assembly number printed on the board itself. Both reference the identical component.
- Q: Do you offer warranty on this board?
- A: Yes. Warranty terms vary by stock condition (new vs. refurbished). Please request warranty details when submitting your inquiry.
- Q: Can you ship internationally?
- A: Yes. We ship globally via DHL, FedEx, and UPS Express. Export documentation including commercial invoices and packing lists are provided for customs clearance.
