ABB 3BSC950202R1 TK821V020 Industrial Backup Power Cable

Product Overview

The ABB TK821V020 (3BSC950202R1) serves as a specialized battery connection cable within the AC 800M controller architecture. This 2-meter industrial-grade cable establishes the critical link between the controller and its backup battery unit, safeguarding volatile memory and system parameters during main power failures. By providing a secure, low-resistance connection, the TK821V020 ensures that the controller maintains its application software and firmware integrity. We supply this component as 100% brand new and original, delivering the ruggedized construction necessary for the continuous operation of high-availability process control systems.

Engineering Advantages

The TK821V020 3BSC950202R1 solves specific power-related reliability challenges in the automation rack:

• Secures Volatile Memory Data: This cable prevents the loss of critical application software and configuration files by maintaining a stable current flow from the backup battery. It ensures the controller retains its "brain" during unplanned outages.

• Extended Reach for Panel Flexibility: The 2-meter length allows engineers to mount the backup battery unit away from the primary controller heat sources or in accessible maintenance areas of the cabinet, bypassing the constraints of standard short cables.

• Industrial-Grade Shielding and Insulation: High-quality insulation protects the power transmission from electromagnetic interference (EMI) and harsh ambient temperatures (up to 70°C). This resilience stops signal noise from affecting the controller’s sensitive internal power monitoring circuits.

• Optimized Connector Design: Proprietary ABB connectors ensure a gas-tight, vibration-proof fit. This prevents accidental disconnections in high-vibration manufacturing environments, such as those found in pulp & paper or oil & gas facilities.

• Swedish Build Quality: Manufactured to original factory tolerances in Sweden, the cable meets the exact gauge and material specifications required by the AC 800M family, unlike generic substitutes that risk voltage drops or connector failure.

FAQs

• Does the TK821V020 include the battery itself?

  No. The TK821V020 is the specialized 2-meter connection cable only. You must order the battery unit separately to complete the backup power assembly for your AC 800M controller.

• Is this a brand new 3BSC950202R1 unit or a refurbished one?

  We only supply 100% brand new and original ABB hardware. Every TK821V020 originates from ABB Sweden and arrives in its original factory-sealed packaging with full traceability.

• Can I use this cable with other PLC families?

  The TK821V020 features connectors specifically designed for the ABB AC 800M series. Using this cable with non-ABB systems may damage the pins or lead to improper power regulation; we recommend use exclusively within the S800/AC 800M ecosystem.

• What is the significance of the 2-meter length?

  Standard battery connections are often quite short. The 2-meter TK821V020 variant provides the necessary slack to organize cabling neatly through vertical or horizontal wire ducts in large-scale control cabinets.
