The versatility of ABB TB805 enables it to pair perfectly with ABB’s core PLC modules (such as AC 800M series and various I/O modules) and adapt to standard control cabinet layouts, facilitating efficient installation, maintenance, and upgrades of automation systems. What sets ABB TB805 apart is its exceptional mechanical stability and electrical reliability under extreme conditions—including industrial vibration, temperature fluctuations, and electromagnetic interference—common in manufacturing, power generation, and process industries. Compact and standardized for DIN-rail mounting, ABB TB805 optimizes space utilization in control cabinets while simplifying wiring management, becoming an indispensable choice for industrial engineers and system integrators worldwide.
- Robust Terminal Connectivity: ABB TB805 features corrosion-resistant copper alloy screw-clamp terminals that ensure secure and long-lasting wire connections, preventing signal loss or connection failure due to industrial vibration or environmental wear.
- High-Capacity Signal Handling: With 32 double-row terminals and 16A current-carrying capacity per terminal, the module supports wiring for multiple I/O signals (analog, digital, power) in one unit, simplifying signal distribution for complex PLC systems.
- Built-In Surge Protection: Integrated varistor surge protection up to 2kV shields connected PLC modules and signal lines from voltage spikes and transient surges, enhancing the overall reliability of the automation system.
- Seamless ABB Ecosystem Compatibility: Designed specifically for ABB’s core PLC and I/O modules, ABB TB805 ensures perfect mechanical and electrical matching, enabling plug-and-play integration and reducing installation errors.
- Easy Maintenance & Wiring Management: The double-row terminal layout and clear labeling scheme simplify wire tracing, replacement, and system upgrades, reducing maintenance time and operational downtime.
- Automotive Assembly Line Control Cabinets: A leading European automotive manufacturer deployed ABB TB805 in its chassis assembly line control cabinets. The module terminated and distributed signals for position sensors, robotic actuators, and safety interlocks, reducing wiring errors by 40% and cutting maintenance time for I/O modules by 30%.
- Thermal Power Plant Auxiliary System Wiring: A large thermal power plant in Asia adopted ABB TB805 for its boiler auxiliary control systems. The module handled wiring for pump status signals, valve control lines, and temperature transmitters, withstanding high-temperature and high-vibration environments and ensuring zero connection-related failures over three years of operation.
- Pharmaceutical Cleanroom Automation: A global pharmaceutical company integrated ABB TB805 into its cleanroom production line control systems. The flame-retardant and dust-resistant design met strict cleanroom safety standards, while the organized terminal layout simplified sterile maintenance and compliance inspections, aligning with FDA and GMP regulations.
- ABB Automation Ecosystem Projects: Prioritize ABB TB805 for projects using ABB AC 800M series PLCs or ABB standard I/O modules, as its native compatibility ensures seamless integration and avoids compatibility issues common with generic terminal bases.
- High-Current Signal Applications: Choose this module for systems requiring terminal current capacity up to 16A (e.g., power control lines, heavy-duty sensor wiring) where generic low-current terminal bases may fail.
- Harsh Industrial Environments: Opt for ABB TB805 for control systems in high-vibration, high-temperature, or electromagnetic interference-prone environments (e.g., power plants, manufacturing lines) due to its robust mechanical and electrical protection.
- Installation: Mount the module on standard 35mm DIN rails in a dry, dust-free control cabinet; ensure the mounting clips are fully locked to prevent displacement due to industrial vibration, and maintain proper spacing from heat-generating components.
- Wiring Safety: Use wires within the specified cross-section range (0.5mm² – 2.5mm²) and torque the terminal screws to the recommended 0.8-1.2 N·m to ensure secure connections without damaging the terminals or wires.
- Surge Protection Maintenance: Periodically inspect the built-in surge protection varistors (via visual checks or multimeter testing) and replace the module if varistors show signs of damage (e.g., discoloration, cracking) to maintain signal protection.
- Storage: Store unused ABB TB805 modules in a cool, dry environment with a temperature range of -10°C to +45°C and relative humidity below 75%, and keep them in the original packaging to prevent mechanical damage or corrosion of terminals.
