Product Details

1336‑148363 is the complete main control CPU board assembly for Allen‑Bradley 1336 series AC drives. As the central computing unit of the drive, it runs core motor control algorithms, stores drive configuration parameters, and handles all local I/O and serial communication tasks.

It receives feedback data from sampling boards, gate drive boards and auxiliary boards, performs closed‑loop speed and torque calculation, and outputs control commands to each functional sub‑board. It collects fault signals from every circuit inside the drive, generates corresponding fault codes for display, and triggers corresponding protection actions.

The board integrates terminal interface circuits for field wiring, supporting direct connection of external start‑stop, speed reference and fault interlock signals. Matches original mounting dimension and connector definition, supports direct replacement. Solves typical faults such as drive boot failure, parameter loss, random fault reporting, I/O channel failure, communication unable to establish. Strict ESD protection must be performed during disassembly and installation to prevent damage to onboard CPU and memory chips.

Suitable for overhaul of legacy fan, pump and conveyor automation equipment.

Remark:Legacy EOL spare component;original production discontinued;please confirm drive horsepower,hardware revision and firmware compatibility before purchase.
