The Allen Bradley SMC‑2 (150‑A Series) Smart Motor Controllers are early-generation solid-state starters designed for reliable three-phase motor control in industrial applications. These units support current ratings up to about 97 A, offer selectable start/stop profiles, and provide compact motor protection. Commonly used in conveyors, pumps, and small machinery, the SMC‑2 provides dependable control where simple soft-start functionality is needed.

These controllers are used to manage motor startup and stopping while reducing inrush current and stress on mechanical systems. They are well suited for pump, fan, and conveyor applications requiring basic soft-start operation.
Example: 150‑A60NBD
150‑A60NBD │ │ │ │ │ │ │ └─ Control options (B/D = 24–240 V AC/DC) │ │ └─ Voltage class (N = 200–600 V AC) │ └─ Current (60 = 60 A) └─ Series (150‑A = SMC‑2)
The SMC‑2 series supports motor currents up to approximately 97 A and is designed for 200–600 V AC systems. Enclosed and open-frame options are available to fit your installation needs.
SMC‑2 units typically provide Soft-Start, Full-Voltage Start, and Current-Limit Start. They include both normal stop and soft stop capabilities, programmable via DIP switches.
Yes—basic electronic overload protection is included, along with diagnostics for phase loss, under- and over-voltage issues, and overload conditions.
No—SMC‑2 controllers do not support network communications. For DeviceNet, EtherNet/IP, or other networked options, you’ll need to choose SMC‑Flex or Dialog Plus series controllers.
