DMA 85B 5311-D

The Bosch Rexroth Indramat DMA 85B 5311-D from the DMA Servo Drive Modules series is a three-phase drive module engineered for precise motor control and seamless integration. It operates with an Input Voltage 670V to deliver an Output Voltage 400V to connected actuators, while its 24 VDC current input of 1.35 A powers the internal logic and control circuits. This module is part of the broader Servodyn-D Series and is optimized for both synchronous and asynchronous motors. With a compact footprint and robust design, the DMA 85B 5311-D excels in demanding industrial environments.

Reliable performance is ensured through built-in thermal management, featuring a backplane with 2 fans that maintain optimal temperature under load. The controller supports selectable switching frequencies of 4 kHz and 8 kHz to balance noise, efficiency, and dynamic response. It tolerates a maximum power loss of 380 W during operation, and global deployment is backed by a one-year warranty. For safe installation, the unit must be mounted in an external switch cabinet rated to IP54 protection and powered via a dedicated supply module with prefabricated cables compliant with Rexroth Indramat specifications.

Ideal for packaging systems, printing machines, assembly systems, and other automation tasks, the DMA 85B 5311-D delivers consistent torque and speed control. Its three-phase architecture and adherence to industrial standards simplify commissioning and minimize downtime. Whether driving servo or asynchronous motors, this module provides the accuracy and durability demanded by modern production lines.
