The TB851 3BSC950194R1 is a CEX-Bus Terminator manufactured by ABB, primarily used in industrial automation systems for terminating CEX-Bus communication lines. Below are its technical specifications in English:

1. General Specifications

• Model Number: TB851
• Order Code: 3BSC950194R1
• Product Type: CEX-Bus Terminator
• Purpose: Used to terminate the CEX-Bus communication line in industrial automation systems, ensuring signal integrity and preventing reflections.

2. Connectivity

• Connector: 25-pin DB25S female connector for CEX-Bus communication.
• Mounting: Designed for DIN rail mounting, allowing easy integration into control panels.
• Fastening: Screw-fastened for secure installation.

3. Dimensions & Weight

• Dimensions:
  • Length: 55 mm
  • Height: 16 mm
  • Width: 45 mm
• Weight: 0.04 kg (40 grams)

4. Electrical & Environmental

• Power Supply: No additional power supply required; operates passively as a terminator.
• Operating Temperature: Not explicitly stated, but typically suitable for industrial environments (-20°C to +70°C, depending on system requirements).
• Protection Rating: IP20 (protected against solid objects >12.5 mm, not waterproof).

5. Application

• Industrial Automation: Specifically designed for use in ABB’s AC 800M series controllers and other compatible systems.
• CEX-Bus Communication: Terminates the CEX-Bus line when communication interface units are mounted on adjacent DIN rails, ensuring proper signal termination.

6. Certifications

• IEC 61508-SIL3 Certification: Part of the AC 800M series, which includes safety-certified controllers for high-integrity applications.

7. Advantages

• Signal Integrity: Ensures reliable communication by terminating the CEX-Bus line, preventing signal reflections and maintaining data integrity.
• Compatibility: Designed for seamless integration with ABB’s AC 800M controllers and other CEX-Bus-compatible devices.
• Robust Design: Suitable for industrial environments, with a focus on durability and reliability.

This terminator is essential in systems where CEX-Bus communication is used, particularly in applications requiring high safety and reliability, such as process automation and safety-critical systems.
