Product Description
Product Overview
The TU818 (Part Number: 3BSE069209R1) is a high-density Compact Module Termination Unit (MTU) engineered for the ABB S800 I/O system. This unit acts as the physical and electrical bridge between S800 I/O modules and field-side wiring, facilitating seamless communication for AC 800M controllers and System 800xA platforms. Designed specifically for space-constrained control cabinets, the TU818 allows for high-density I/O configurations without compromising signal integrity or mechanical robustness. It supports various I/O types, including digital and analog signals, providing a centralized point for power distribution and signal routing in complex industrial automation environments.

Operational Advantages and Reliability
-
Space-Efficiency: The compact footprint of the TU818 allows for more termination points per linear meter of DIN rail, making it ideal for high-density cabinet modernization projects.
-
Vibration and EMI Resilience: Constructed with high-grade industrial insulation, this MTU effectively shields sensitive I/O signals from electromagnetic interference (EMI) and mechanical vibration typical in power and metallurgy sectors.
-
Simplified Maintenance: The module-to-baseplate design allows for the hot-swapping or replacement of I/O modules without disturbing the field wiring, significantly reducing Mean Time to Repair (MTTR).
-
Secure Signal Routing: Supports organized wiring for DI, DO, AI, and AO signals, reducing the risk of wiring errors during commissioning and troubleshooting.
Typical Application Scenarios
-
Power Generation: Reliable signal termination for turbine and boiler control loops.
-
Chemical Processing: Robust performance in environments requiring high thermal and chemical resistance.
-
Water Treatment: Cost-effective and high-density signal management for distributed pump stations.
-
Metallurgy: Stable operation in high-heat and EMI-heavy smelting environments.
