Product Details

1336‑140311 is SCR firing control PCB board for Allen‑Bradley 1336 series ac drive. It generates precise trigger pulses to drive the input rectifier SCR modules,realizes phase‑angle control for AC‑DC rectification process.

It monitors input power condition and feeds rectifier working status back to main control board. Matches original installation dimension and interface,supports direct replacement without extra modification. Solves typical faults including rectifier abnormal,dc‑bus cannot build‑up,input phase loss alarm. ESD protection is required during installation.

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

Remark:Legacy EOL spare component;original production discontinued;please confirm drive compatibility before purchase.
