The Hägglunds MDC 214 1080-801 is a specialized Motor Displacement Control (MDC) circuit board designed for high-performance hydraulic systems, particularly those found in deck cranes and other heavy-duty marine and industrial machinery.

This PCB (Printed Circuit Board) acts as an interface that manages hydraulic motor displacement, ensuring precise control over speed, torque, and movement. It is often found integrated within larger MacGregor-Hägglunds drive and control platforms.

Key Product Specifications

• Model Number: MDC 214 1080-801

• Primary Function: Regulates hydraulic motor displacement for accurate motion control.

• Compatibility: Frequently associated with MacGregor-Hägglunds deck crane systems and hydraulic drive control racks.

• Weight: Typically around 270g – 300g.

• Applications: Marine vessel deck cranes, heavy-duty industrial hydraulic actuators, and mobile mining/construction equipment.

 

Frequently Asked Questions (Q&A)

💡 What does the MDC module actually do?

It monitors and adjusts the fluid displacement within the hydraulic motor. By precisely controlling this, the module allows for smooth acceleration, deceleration, and positioning of heavy loads in applications like crane hoisting and slewing.

💡 Is this module “plug-and-play”?

These modules are generally part of a complex control rack system. While they are physically swappable, they often require proper calibration within the system’s controller (such as a Pump Control module or Supervisory Logic unit) to ensure correct operation with your specific crane’s hydraulic parameters.

💡 Why am I seeing different part numbers like 314 2693-001 A?

In industrial automation, you may see a “Model” number (MDC 214 1080-801) and a “Part” or “Assembly” number (e.g., 314 2693-001 A) on the same board. Always verify both against your existing module to ensure the specific revision is compatible with your current installation.

💡 Where are these typically sourced?

Because these are specialized components for legacy or specific marine systems, they are often available through industrial automation surplus suppliers rather than retail storefronts. Ensure you purchase from reputable suppliers that offer documentation or “runner” verification (boards removed from working systems).
