AB controller is a programmable logic controller (PLC), mainly used in the field of industrial automation.

AB controllers are mainly divided into three categories according to their size:

Small: MicroLogix controller

Medium: CompactLogix controller

Large: ControlLogix controller

AB controllers also have a wide range of applications, such as MicroLogix controllers for the basic control needs of simple machinery, including relay replacement and simple control timing and logic; CompactLogix controller for mid-range applications; ControlLogix controllers are suitable for large applications.
