Product Profile – ABB TU836V1 (3BSE013237R1)
1. Product Introduction
The TU836V1 (3BSE013237R1) is a high‑density termination unit designed for structured field wiring in industrial automation and process control systems. It provides a central connection point between numerous field devices — such as sensors, switches, and actuators — and the internal distributed I/O modules of programmable controllers or distributed control systems.
As automation systems grow in complexity, the number of field signals that must be organized and reliably connected also increases. The TU836V1 helps streamline this complexity by offering orderly grouping of up to 48 channels while maintaining a compact and maintainable form factor. Its design emphasizes secure electrical connections, mechanical guidance to prevent incorrect placement, and durable operation in demanding environments.
