Allen Bradley 1769-SM2 Compact I/O to DSI Module

Product Introduction

The Allen-Bradley 1769-SM2 Compact I/O to DSI Module is a communication interface module designed for integration within the Compact I/O platform developed by Allen-Bradley. The module provides a communication bridge between CompactLogix controllers and motor drives that use the DSI (Drive Serial Interface) protocol. Through this connection, the controller can exchange operating commands, status information, and diagnostic data with compatible drive devices.

Installed directly into the Compact I/O backplane, the 1769-SM2 operates as part of the system’s modular architecture and receives its operating power from the backplane bus. This design simplifies system wiring and allows the controller to manage drive communication within the same automation platform.

The module is commonly used in industrial automation systems where motor drives must be monitored and controlled by a PLC. By enabling direct integration between the controller and DSI-based drives, the module helps improve system visibility, simplify configuration, and support stable drive operation in machine control and process automation environments.
