Allen-Bradley 40888-490-01-A1FX SMC Dialog Plus Module – Reliable Motor Control Interface

Product Overview

The Allen-Bradley 40888-490-01-A1FX is a control module designed for use with the Bulletin 150 SMC Dialog Plus series of solid-state motor controllers. Manufactured by Allen-Bradley (Rockwell Automation), the Allen-Bradley 40888-490-01-A1FX serves as a critical interface component within the SMC Dialog Plus controller architecture, providing the control logic and interface functions that enable soft start, pump control, and other advanced motor starting modes.

The SMC Dialog Plus series represents Allen-Bradley‘s established line of microprocessor-based motor controllers, designed to provide a comprehensive range of starting modes including soft start with selectable kickstart, current limit start, dual ramp start, and full voltage start. Within this ecosystem, the Allen-Bradley 40888-490-01-A1FX functions as a standard control module variant that integrates with the controller chassis to deliver the programming, monitoring, and control interface capabilities required for effective motor management.

The Allen-Bradley 40888-490-01-A1FX is distinguished by its compatibility with the broader SMC Dialog Plus platform, which supports motor ratings from 1 to 1000 Amps across voltage ranges of 200 to 600 Volts AC. The controller’s built-in keypad and LCD interface, accessible through the module, enables configuration and monitoring without requiring external programming tools, making the Allen-Bradley 40888-490-01-A1FX a practical solution for both new installations and maintenance replacements in existing SMC Dialog Plus systems. Documentation references indicate the module is associated with the SMC Dialog Plus user manual, which covers power module pin identification and component testing procedures.
