Description
The 1336-QOUT-SP19A is an internal output-stage assembly for Allen-Bradley (Rockwell Automation) Bulletin 1336 adjustable frequency AC drives, identified by its QOUT designation — the transistor output assembly rather than the control board. It is the power-switching section that generates the drive’s three-phase output to the motor.
The part is a board-level spare intended to replace a failed output stage inside the drive enclosure. When an IGBT, gate-drive component or associated protection device on the output assembly fails, replacing the complete drive is rarely necessary; the 1336-QOUT-SP19A is the correct Level 1 spare for that failure mode. It is listed against the 1336 PLUS and PLUS II families and also reported as compatible with 1336 FORCE, IMPACT and REGEN drives in the same output-stage group.
Application Scenarios
A water utility’s 575 V booster station lost one of three 1336STEF drives during a storm-related supply disturbance. The drive displayed an output-stage fault and would not reset, but the motor, cabling and upstream protection were intact. Removing the enclosure revealed one damaged device on the output assembly and no other faults. Replacing the output-stage assembly returned the drive to service for a fraction of the cost and lead time of a complete unit. The key decision was made in the first hour: check the output assembly before condemning the whole drive.
The same reasoning applies across the installed base. A pulp mill running multiple 1336 PLUS drives on conveyors and refiners keeps 1336-QOUT-SP19A assemblies on the shelf alongside main control boards and cooling fans. When an output fault appears, the maintenance team swaps the assembly, transfers the jumpers and option hardware from the old board, and runs a controlled start before returning the machine to production. The alternative — ordering a complete obsolete drive — would leave the line waiting for a part that is no longer in regular production.
