Applications & Industry Context
Variable Frequency Drives (VFDs) are at the heart of modern motor control, and when one component fails, the entire production line can come to a standstill. That’s where the Allen Bradley 1336-BDB-SP79D comes in. As a replacement control board for 1336 series drives, it ensures that critical equipment can be restored quickly and reliably.
In manufacturing plants, 1336 drives are widely used to regulate motors on conveyors, mixers, pumps, and fans. In food processing, they keep mixers running at precise speeds to ensure product consistency. In wastewater facilities, they optimize pump operation to reduce energy consumption while maintaining reliable flow.
Downtime in these industries is costly. A packaging line with multiple VFDs might lose thousands of dollars per hour if even one unit goes offline. Having the 1336-BDB-SP79D Allen Bradley board available allows maintenance teams to replace faulty electronics without the need to swap out the entire drive. This not only saves costs but also keeps legacy systems running long after original commissioning.
Product Role & System Fit
The 1336-BDB-SP79D is designed to fit seamlessly into the 1336 family of adjustable frequency drives. These drives were a workhorse of the Rockwell Automation product line, offering robust motor control across a wide range of horsepower ratings.
Within each drive, the control board plays a critical role. It manages signal processing, logic execution, and communication between the drive’s power electronics and external controllers. When the original board begins to show signs of failure — intermittent faults, loss of communication, or inconsistent motor response — replacing it with the OEM-designed Allen Bradley 1336-BDB-SP79D restores the drive’s full functionality.
Its role is particularly important in facilities that rely on legacy equipment. While newer PowerFlex series drives have taken the lead in recent years, thousands of 1336 series drives remain in service worldwide. The 1336-BDB-SP79D provides a cost-effective way to extend their operational life without full system replacement.
Technical Features & Benefits
The Allen Bradley 1336-BDB-SP79D board is built with precision and compatibility in mind. Unlike generic replacements, it is manufactured to meet Rockwell’s strict quality and reliability standards.
Key features include:
- Direct compatibility with 1336 series drives — ensures seamless installation without modification.
- OEM-tested reliability — each board is validated for industrial duty, guaranteeing performance in high-demand environments.
- Restored drive functionality — corrects common issues such as faulty logic processing, erratic control signals, or failed communication ports.
- Reduced downtime — enables quick repair of drives already installed in the field.
- Long lifecycle support — provides a bridge for facilities using legacy systems while planning gradual migration to newer platforms.
End users often emphasize how replacing the control board rather than the entire VFD reduces costs dramatically. Instead of sourcing a full new drive, which might also require rewiring and reprogramming, the 1336-BDB-SP79D module restores functionality in a fraction of the time and at a fraction of the cost.
Installation & Maintenance Insights
Swapping in the Allen Bradley 1336-BDB-SP79D control board is a relatively straightforward task for qualified technicians. Before starting, power must be completely removed from the drive, and lockout/tagout procedures followed.
When removing the old board, engineers should note connector orientation and wiring harness positions. Installing the new 1336-BDB-SP79D requires careful handling to avoid static discharge, ideally using a grounded wrist strap and ESD-safe tools. Once seated and secured, connections can be reattached and the drive re-energized.
Maintenance teams often keep these boards in their spares inventory. Because drive downtime can cripple operations, having a replacement on-site ensures fast recovery. Routine inspections of the drive cabinet, proper cooling, and dust prevention all extend the life of both the drive and the control board.
