3BSE036714R1 TU813 ABB | 25-Pin D-sub Termination Unit

Product Description

Product Overview

The TU813 (Ordering Code: 3BSE036714R1) is a high-integrity Compact Module Termination Unit (MTU) engineered for the ABB S800 I/O system. Specifically designed for high-voltage applications, it features a rated isolation of 250V, making it a critical interface for AC 800M controllers and System 800xA environments. The TU813 serves as a passive baseplate that facilitates both signal connection to field devices and ModuleBus distribution. Unlike standard terminal-based units, this model utilizes a 25-pin D-sub connector for field wiring, providing a rapid, secure, and vibration-resistant connection point ideal for high-density control cabinets.
