Allen-Bradley 150-B97NBD Programmable Logic Controller Module

Allen-Bradley 150-B97NBD is a Soft Start/Smart Motor Controller from the SMC Dialog Plus family, engineered to start and run 3‑phase motors with a controlled ramp from 200 to 480 VAC. Rated for up to 97 A on the line, it reduces inrush current and mechanical stress during startup and acceleration, helping extend motor life and stabilize electrical demand in industrial controls. The device supports a 24 V AC/DC control circuit for straightforward integration with standard automation I/O. As a Bulletin 150 soft-start solution, the 150-B97NBD is designed for use in panel-mounted motor drive applications where smooth, reliable motor start/stop is critical, and it is commonly referenced in distributor catalogs and repair/replacement listings, reflecting its role as a widely used medium-current soft-start for industrial equipment.
