Description

The Siemens 6ES5185-3UA13 (EU185) is a high-capacity 21-slot expansion subrack designed for the Simatic S5-135U and S5-155U programmable logic controller systems. This robust chassis provides the necessary physical mounting and backplane communication infrastructure to extend I/O capabilities in large-scale industrial automation environments. Featuring an integrated 110/230 VAC power supply, the unit delivers stable, regulated power directly to the backplane, supporting high-density configurations of digital, analog, and communication modules without overloading the primary controller rack.

Features

  • 21-slot capacity for extensive I/O and communication module integration.
  • Integrated multi-voltage power supply (110/230 VAC selectable).
  • Designed for seamless integration with Simatic S5-135U and S5-155U systems.
  • Heavy-duty aluminum alloy construction for structural integrity and EMI shielding.
  • Parallel bus architecture ensuring deterministic signal timing and high-speed data transfer.

Applications

This expansion subrack is engineered for critical industrial infrastructures requiring high-density I/O, including thermal power plants, oil and gas refining units, and heavy manufacturing control systems. It is ideal for system expansion or as a direct replacement for legacy S5 rack hardware to maintain operational continuity.

Installation Guidelines

  • Ensure the subrack is mounted in a clean, dry, and vibration-free environment within an industrial cabinet.
  • Verify that the power supply input voltage selector is correctly set to match the local supply (110 VAC or 230 VAC) before applying power.
  • Always power down the system before inserting or removing modules to prevent electrical damage to the backplane connectors.
  • Ensure proper grounding of the chassis to the cabinet frame to maintain EMI protection and safety.
  • Maintain adequate clearance around the unit to allow for natural convection cooling.

FAQ

Is this subrack compatible with all S5 modules?

The 6ES5185-3UA13 is designed for standard Simatic S5-135U/155U modules. Please verify the physical form factor and electrical requirements of your specific I/O modules against the S5 system documentation.

Does this unit require an external power supply?

No, this unit features an integrated power supply that accepts 110/230 VAC line power and converts it to the required internal DC bus voltages.
