System Integration

The integration of the LEDEEN electric actuators into a control system is possible via a multitude of fieldbus connections or via a free-configurable, hard-wired interface. All fieldbus devices can be delivered with the common redundancies, to help enhance system safety and reliability.

SIMA Master Station

  • System Integration -The SIMA master station solution integrates field devices, like actuators, into an automation environment and supports a variety of protocols such as PROFIBUS DP and Modbus RTU.
  • Data Concentrator - In addition to the essential feedback information, our LEDEEN DiM series electric actuators provide a wide variety of data that can be used by the SIMA master station to quickly and easily diagnose the system with reduced stressing.
  • Commissioning Tool - SIMA also functions as a standalone automation system, allowing the actuator to be operated and commissioned autonomously from a higher automation system. Actuator and communication parameter settings can be performed and tested.
  • Redundant Security - To allow for enhanced safety operations, the SIMA master station has been designed as a highly redundant unit with both the master unit and the cables being redundant in case of a failure.
