Configured for single-axis drive control execution in Allen-Bradley ControlLogix automation platforms, the Allen-Bradley 1756-DMD30 (1756-DMD30 Drive Control Module) provides direct motion control processing through fiber optic communication and 24 VDC interface circuits.

Model Configuration Details

The 1756-DMD30 is a ControlLogix drive module designed for one-axis drive control applications. The module provides drive interface functionality with LED status indicators, fiber optic communication capability, and a 24 VDC power interface.

The module requires 1.35 A at 5.1 VDC from the ControlLogix backplane and provides a dedicated hardware interface for motion-related control operations within compatible ControlLogix chassis configurations.

Hardware Specifications

ControlLogix Motion Communication Characteristics

The 1756-DMD30 uses Allen-Bradley industrial control architecture for drive communication and single-axis control applications. The module supports firmware flash compatibility considerations when integrated into existing ControlLogix systems.

Fiber optic communication provides an interface path for drive-related data exchange, while the ControlLogix backplane manages module communication and controller data processing. Proper chassis configuration and controller firmware matching are required during system integration.

Ordering Information

The standard shipment configuration includes:

• 1 x Allen-Bradley 1756-DMD30 ControlLogix Drive Control Module
• 1 x Factory product identification label
