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.
Brand: ABB Professional Electrical Instruments
Series: S800 I/O – High‑Density Module Termination Units (MTU)
The S800 I/O series is a modular distributed I/O platform widely used in industrial automation, machine control, utilities, and infrastructure. Module Termination Units (MTUs) like the TU836V1 serve as bridges between field wiring and functional I/O modules, enabling scalable, flexible, and maintainable system architectures.

The TU836V1 termination unit is suited for industrial automation environments where a large number of field signals must be reliably connected and efficiently organized. Typical applications include:
• Distributed I/O systems for PLC, DCS, and RTU control architectures.
• Medium to large‑scale machine control panels requiring high channel capacity.
• Process automation in chemical, manufacturing, and energy distribution systems.
• Field signal consolidation in infrastructure automation such as water treatment, power plants, and transportation control.
• Retrofit and expansion of legacy systems to modular distributed I/O platforms.
• Automated systems where neat wiring and rapid maintenance turnaround is critical.
The TU836V1 delivers several practical advantages for system designers and engineers:
• High Channel Density: With 48 channels, it handles extensive field wiring without requiring excessively large panel space.
• Secure Electrical Termination: Screw‑type terminals provide robust contact and low electrical resistance.
• Mechanical Keying: Helps prevent incorrect module insertion and wiring errors during installation and service.
• DIN‑Rail Compatibility: Standard DIN‑rail mounting supports rapid installation, modification, and replacement.
• Organized Wiring Layout: Grouped channels and clear labeling support documentation, commissioning, and ongoing maintenance.
• Industrial Suitability: Wide operating temperature range and durable materials ensure dependable operation in harsh environments.
• Modular Scalability: Integrates with other termination and I/O modules in the same family for flexible system design.
• Maintenance Friendly: Structured channel layout simplifies fault isolation and future expansion.
