Product Profile – ABB TU847Z (3BSE035338R1)
1. Product Introduction
The TU847Z (3BSE035338R1) is a high‑capacity termination and interface unit designed for organizing large numbers of field connections in industrial automation, distributed I/O, and control applications. It serves as a structured field termination point between external field devices — including sensors, switches, actuators and other signal sources — and internal I/O modules of a programmable logic controller (PLC), distributed control system (DCS), or remote terminal unit (RTU).
This termination unit is built to handle significant signal density while maintaining clear wiring organization and ease of maintenance. It provides reliable electrical contacts, mechanical safeguards to prevent installation errors, and industrial‑grade construction to withstand demanding environments.
2. Brand and Series Information
Brand: ABB Professional Electrical Instruments
Series: S800 I/O – Module Termination Units (MTU)
The S800 I/O series is a modular distributed I/O platform used in industrial automation, process control, machine control, utilities, and infrastructure systems. Termination units like the TU847Z serve as the physical interface where field wiring connects to modular I/O components.
