Description

The Allen-Bradley 1756-DMF30 is a specialized single-slot drive interface module designed for the ControlLogix platform. This module functions as a high-speed communication and control bridge between a ControlLogix processor and the Reliance Electric Distributed Power System (DPS) hardware. It coordinates complex outer-loop control algorithms, including precise torque, position, and velocity control, by interfacing directly with a field-mounted Power Module Interface (PMI) chassis via a dedicated fiber optic link.

Features

Designed for seamless integration with the ControlLogix backplane.
Supports high-speed communication for complex drive control loops.
Fiber optic interface for reliable communication with remote PMI chassis.
Optimized for legacy Reliance Electric drive system migrations.

Drive System Compatibility

The 1756-DMF30 is engineered to support legacy high-power Reliance Electric drive systems, including:

SD3000 6-Pulse DPS: Interfaces with S6 DC drives and S6R resolver assemblies.
SD3000 12-Pulse DPS: Connects with S12 DC drives and S12R resolver configurations.
