SMC-2 Smart Motor Controller

The SMC-2 Smart Motor Controller series from Allen Bradley is a family of solid-state motor controls used to start and manage AC induction motors in industrial applications. These units provide soft-start functionality, offering controlled acceleration that reduces mechanical stress and inrush current compared with across-the-line starting.

The series spans a broad range of current ratings, from compact SMC-2 modules rated for fractional-horsepower and low-amperage motors up to 240A SMC Plus control bases for larger loads. All products carry Allen Bradley 150-A catalog numbers and are cataloged as Motor Controls.

Product Range

• SMC-2 modules and controls — including 9A soft-start modules and units rated from 1/3 to 3 HP.
• SMC Plus / Smart Motor Control units — available in ratings such as 24A, 35A, 54A, 68A, 97A, and 240A.
• SMC Plus control bases — including 97A and 240A versions.

The series includes multiple configuration variants within each current rating, distinguished by catalog suffix. These controllers are commonly applied where smooth motor starting and reduced electrical and mechanical shock are required.
