ABB TB805 Bus Socket Module

Product Description

The ABB TB805 (3BSE008534R1) is a bus socket module designed for integration with ABB's AC500 PLC systems, particularly in safety-critical applications. It serves as an adapter interface for connecting I/O modules or communication devices within industrial automation networks, supporting both safety and non-safety functions in a unified hardware platform .

Key Features

1. Hybrid Compatibility:

   • Allows mixing of safety and standard I/O modules in the same PLC system, reducing complexity and cost .

   • Consistent dimensions and installation schemes with other ABB AC500 modules .

2. Safety-Certified:

   • Complies with SIL3/PL e safety standards for industrial control systems .

   • Supports PROFINET/PROFIsafe protocols for secure communication in networked environments .

3. Modular Design:

   • Facilitates easy expansion with additional I/O modules or communication interfaces (e.g., CI801, CI840) .

   • Compatible with ABB’s AC500-S safety PLCs, enabling direct variable mapping between safety and non-safety systems .

4. Robust Performance:

   • Designed for industrial environments with wide operating temperature ranges and high EMI resistance.

Technical Specifications

• Model Number: TB805 (3BSE008534R1) .

• Compatibility: AC500 PLC series, including safety CPUs like PM803F and redundancy modules .

• Communication Protocols: PROFINET, PROFIsafe (for safety-rated data exchange) .

• Mounting: DIN rail or panel mounting (standard AC500 form factor) .

• Certifications: TÜV SüD-tested for IEC 61508-3 compliance .

Applications

• Safety Systems: Emergency stops, crane controls, and machinery safety interlocks .

• Process Automation: Integration with ABB System 800xA for distributed control .

• Remote I/O: Deployed in PROFINET-linked I/O racks to reduce wiring costs .

Usage Notes

1. Installation: Ensure proper termination of bus cables (e.g., TB850/TB851 terminal resistors) to avoid signal degradation .

2. Configuration: Use ABB’s Safety Code Analyzer (SCA) tool for IEC 61508-3-compliant programming .

3. Maintenance: Regularly check connections for corrosion or loosening, especially in high-vibration environments.

Related Accessories

• Communication Modules: CI801, CI840A (redundant option) .

• Cables: TK811F (communication), TK851V010 (redundant controller link) .

• Terminals: TB870F connection terminal board .
