Description

Siemens 3RK1903-3AE00 Terminal Module

Product Dimensions：

The Siemens 3RK1903-3AE00 is a specialized connection component within the SIRIUS industrial control family. Specifically, it is a Bus Termination Module (also known as a Terminator) for the ET 200pro distributed I/O system.

Product Detailed Description

The 3RK1903-3AE00 is designed to terminate the internal data bus of an ET 200pro station. In a modular distributed I/O setup, signal integrity is maintained by ensuring the bus ends correctly. This module is physically installed at the end of the module rack to close the backplane bus, allowing the interface module to communicate effectively with all electronic modules in the stack.

Technical Parameters

Product Advantages

• Ruggedized Protection: With an IP67 rating, this module is designed for “cabinet-free” installation, meaning it can be mounted directly on a machine in harsh environments without an extra protective enclosure.
• Plug-and-Play: Requires no complex wiring or software configuration; it simply clips onto the end of the ET 200pro rack to complete the circuit.
• High Reliability: Ensures stable data transmission across the backplane by preventing signal reflections and electrical noise at the end of the bus.
• Compact Design: Matches the form factor of the ET 200pro series, maintaining a clean and uniform hardware profile.

Important Considerations (Precautions)

• Essential Component: An ET 200pro station cannot function without a termination module. If this module is missing or damaged, the Interface Module (IM) will report a bus error and the station will not start.
• Physical Placement: It must always be the final module on the right-hand side of the rack assembly.
• Seal Integrity: Ensure the module is properly seated and the locking mechanism is engaged to maintain the IP67 water-resistance rating.
• No I/O Functionality: Note that this is a passive termination module; it does not provide any digital or analog inputs/outputs.

Product Applications

This module is used exclusively within the SIMATIC ET 200pro system across various industries:

• Automotive Assembly: Used on conveyor lines where modules are mounted directly on the frame rather than in bulky electrical cabinets.
• Logistics & Warehousing: Integration into automated sorting systems where high IP ratings are needed for wash-down or dusty environments.
• Machine Tooling: Providing communication termination for decentralized I/O on CNC machines or large-scale industrial presses.
