Allen-Bradley 150-ND Interface Board

The Allen-Bradley 150-ND Interface Board is an installation-ready interface module designed for use with 5..16A SMC-2 motor controllers, adding a Soft Stop function and an auxiliary contact to extend control options. It provides a 120 V control-voltage input and is specified for 200..600 V line voltage, enabling direct integration with standard plant power rails and external interlock or signaling circuits. This 150-ND is listed as a Series A interface option for Allen-Bradley SMC-2 drives, helping coordinate drive signaling with safety interlocks and remote control devices. Common applications include systems requiring controlled stopping and signaling between the drive and external circuitry, such as conveyors, packaging lines, and machine tools where accurate deceleration and status monitoring are important. The module is designed to simplify wiring by consolidating interface functionality in a single board, reducing panel complexity and improving reliability of interconnections between the SMC-2 controller and peripheral devices.
