Allen-Bradley 1336T-MCB-SP Main Control Board Unit

Module Feature

1336T-MCB-SP is the main control board manufactured by Allen-Bradley (Rockwell Automation),designed exclusively for 1336 FORCE series AC variable frequency drives. It executes V/F and vector control algorithms,processes analog and digital I/O signals,stores drive parameter sets and records fault history. Equipped with communication interface for optional fieldbus adapters and keypad connection port. Widely used as spare replacement part for conveyor,fan,pump and process control 1336T drive maintenance.

Working principle

Receives speed/torque command signals and feedback data,calculates PWM reference signals to control power module switching. Continuously monitors bus voltage,output current and temperature feedback from power section,triggers protection actions once abnormal conditions are detected. It communicates with operator keypad and optional network adapter for parameter setup and status upload.

Onboard components

Main microprocessor chip,non-volatile parameter memory,analog signal sampling circuit,digital I/O logic circuit,serial communication interface,LED status indicator circuit,connector terminals for power board and keypad.
