Product Overview

The ABB TK821V020 (Product ID: 3BSC950202R1) is a specialized prefabricated battery cable designed for the AC800M controller series. This 2.0-meter cable provides the vital electrical link between the controller and its backup battery unit, ensuring data retention and system state persistence during power interruptions. As a critical component for high-availability control architectures, the TK821V020 maintains power integrity for volatile memory sets. We supply this unit as 100% Brand New and original equipment, sourced directly from certified warehouses in Sweden and the USA to ensure immediate reliability for your mission-critical automation.

Technical Specifications

Engineering Advantages

The TK821V020 addresses the specific electrical requirements of the AC800M platform, focusing on low-resistance transmission and mechanical security.

• Optimized Power Retention: The 2.0-meter length allows for flexible battery placement within the control cabinet while maintaining a low-impedance path. This ensures that the battery delivers the required voltage to the CPU RAM without significant drop-off.

• Factory-Terminated Integrity: As a prefabricated cable, the TK821V020 eliminates the risks of manual crimping or improper soldering. Factory-sealed connectors ensure a vibration-proof fit into the AC800M battery port, preventing accidental disconnects in high-vibration environments.

• Strict Manufacturing Standards: Sourced from ABB’s Swedish and German production lines, this cable adheres to the highest European industrial standards. It utilizes high-grade insulation to resist the thermal stress common in densely packed DCS cabinets.

• Standardized System Fit: The TK821V020 matches the exact pinout and mechanical housing of the AC800M series. This "plug-and-play" capability reduces commissioning time and prevents damage to sensitive controller ports caused by non-standard cabling.

FAQs

• What is the exact length of the TK821V020?

  The V020 designation indicates a 2.0-meter length (2,0 m). This provides sufficient reach for routing through cable trays from the controller to a bottom-mounted battery pack.

• Does this cable work with all AC800M controllers?

  The TK821V020 serves the standard battery backup interface for the AC800M family. Always check your specific CPU module's technical manual to verify the connector type matches the 3BSC950202R1 specification.

• Is this a Brand New original ABB part?

  Yes. We supply only 100% Brand New original ABB cables in factory-sealed condition. We do not sell refurbished or used cables for battery backup systems, as cable integrity is vital for preventing data loss.

• How quickly can you ship via FEDEX or DHL?

  We maintain stock at major warehouses in Västerås, Sweden, and Wickliffe, Ohio. This allows us to offer expedited global shipping with typical lead times of 1-2 weeks or less, depending on your location.
