The Allen-Bradley 1769-SM2 is a versatile Compact I/O module designed for integration with CompactLogix and MicroLogix 1500 controllers, featuring Drive Serial Interface (DSI) and MODBUS RTU communication protocols. This module enables seamless communication with PowerFlex 4-class and 7-class drives using a 20-HIM-H-RS485-HVAC adapter. It functions efficiently in both single and multi-drive modes, supporting MODBUS RTU transmission rates up to 38,400 bps, and offers a maximum installation distance of 10 meters for drive connections and 1,219 meters for network wiring. With a compact design, three connection channels for PowerFlex 4-Class drives, and a power consumption of 350 mA at 5V DC, the 1769-SM2 is optimized for expanding local or remote I/O configurations, although it must reside within four modules of the power supply in non-volatile environments.
