Overview
The Allen-Bradley 150-ND interface module is a control accessory designed for the SMC-2 series of soft starter controllers. When installed on compatible SMC-2 units, this 120V AC single-phase interface module enables soft stop functionality and provides auxiliary contact capability. The 150-ND /A revision is commonly paired with larger horsepower SMC-2 controllers to add load-sensitive deceleration and electrical isolation features without requiring an external contactor.
Key Features
- 120V AC single-phase input voltage rating for interface control signal
- Enables soft stop motor deceleration mode on compatible SMC-2 controllers
- Provides auxiliary contact for motor starter isolation and control logic
- Reduces panel space by eliminating need for separate contactor on many applications
- Solid-state design integrates seamlessly with Bulletin 150 SMC-2 series
- New in box condition—immediately ready for installation
Technical Specifications
- Interface Module Voltage Rating: 100–120V AC (+10%, −15%), single-phase
