1336-BDB-SP6A PCB Gate Drive Board Kit: The Gate Pulse Engine for Allen-Bradley 1336 Series Drives

Description

Application Scenarios

In a large material handling facility, a fleet of conveyor systems powered by Allen-Bradley 1336 PLUS II drives experienced recurring faults during high-inertia deceleration cycles. The drives would occasionally trip on overcurrent events, causing unexpected stoppages and disrupting the facility’s continuous logistics operations. Maintenance engineers traced the root cause to degraded gate drive signal integrity—the aging 1336-BDB-SP6A boards were producing inconsistent switching pulses, leading to uneven current sharing across the inverter bridge during dynamic braking.

Replacing the worn boards with new 1336-BDB-SP6A kits restored proper gate pulse timing and amplitude. The facility reported a 70% reduction in drive fault events over six months of operation, with conveyor availability improving to over 99.5%. The maintenance manager noted that the board’s complete kit format—with all gate drive components pre-soldered and tested—eliminated the field assembly errors that had plagued previous repair attempts.

In another case, a paper mill operating winder drives on a 1336 FORCE platform required precise torque control during high-speed reel changes. The existing 1336-BDB-SP6A boards exhibited signal drift that caused tension fluctuations and occasional web breaks. After installing replacement kits, the winder achieved stable tension control throughout the acceleration and deceleration profiles, reducing web breaks by 85% and enabling higher production speeds on specialty paper grades.
