ABB TK821V020 3BSC950202R1 S800 I/O Controller External Battery Connection Cable

Description

The TK821V020 3BSC950202R1 is a 2.0-meter cable providing a secure DC voltage path from a backup battery to the memory protection circuit of ABB System 800xA controllers. It ensures a seamless transition to battery power when the main 24V supply is lost, preventing data loss. With flexible conductors for easy routing in control cabinets and vibration-proof connectors, it guarantees reliable performance, allowing AC 800M or S800 controllers to restart without needing to reload application software.
