Allen-Bradley SMC-2 Drive Control Interface Module

Allen-Bradley SMC-2 Drive Control Interface Module (150-NA) is an interface accessory for SMC-2 drive controllers that provides external ON/OFF control, a selectable auxiliary contact, and Soft Stop to smoothly decelerate motors powered from 240 VAC. The interface uses three control wires and is configured for 240 V control voltage with 240 V line voltage, designed to plug into the SMC-2 family to enable remote start/stop and interlocking in automation systems. In operation, start and stop signals are typically wired to the controller’s terminals 10 and 30, respectively, allowing an external device or control panel to govern motor operation while the drive retains its protective features. This module delivers a straightforward way to add external control, signaling, and safety interlocks to legacy Allen-Bradley SMC-2 installations, supporting applications such as conveyors, material handling, and other industrial equipment that require explicit interface options for motor control.
