## Long description

The Siemens ILM ST Direct Starter 3.5-32 A (Size S0) is an advanced intelligent link module designed for the seamless integration of motor load feeders into the SIMATIC ET 200SP automation system. This component serves as a plug-and-play solution for direct-on-line starting, facilitating efficient motor control and monitoring within industrial environments. By connecting directly with compatible circuit breakers and contactors, it enables comprehensive data acquisition and status reporting, ensuring high transparency and operational reliability across the entire automation architecture.
Advantages
This intelligent link module significantly optimizes control cabinet assembly by reducing complex wiring requirements. Its integration into the Totally Integrated Automation (TIA) environment allows for streamlined parameterization and commissioning via the TIA Portal. The device provides real-time diagnostic capabilities, including the detection of faults and operational deviations, which supports proactive maintenance strategies. Its compact S0 frame size ensures space-efficient installation while maintaining high performance for motor currents between 3.5 and 32 A.
Suitable for
Direct-on-line starting of electric motors in industrial automation
Integration of load feeders into SIMATIC ET 200SP systems
Applications requiring remote monitoring and diagnostic data
Preventive maintenance and fault detection in electrical systems
When it may not be suitable
This module is specifically designed for integration with the SIMATIC ET 200SP system and compatible Siemens motor starters. It may not be suitable for standalone applications that do not utilize this specific automation ecosystem or for motor currents outside the specified 3.5 to 32 A range.
Key specifications
Current range: 3.5 to 32 A
Frame size: S0
Maximum operating voltage: 690 V AC
System compatibility: SIMATIC ET 200SP
Functionality: Direct-on-line starting and diagnostic data acquisition
How to use
Installation involves mounting the module in conjunction with compatible Siemens circuit breakers and contactors to form a complete load feeder. Once physically installed, the module is connected to the ET 200SP system. Configuration and parameterization are performed through the TIA Portal software, which allows for the setup of monitoring thresholds and communication parameters to ensure the unit functions correctly within the broader automation network.
What to consider before purchase
