Product Overview
The TU834 (Part Number: 3BSE040364R1) is an Extended Module Termination Unit (MTU) designed for the ABB S800 I/O system. It serves as the critical physical and electrical interface between field wiring and industrial I/O modules. The TU834 (3BSE040364R1) is engineered to provide secure termination points for up to 16 channels, supporting a wide range of signals including analog inputs (AI), analog outputs (AO), and digital inputs/outputs (DI/DO). Its "Extended" design allows for additional wiring space or specific signal conditioning accessories, making it an essential component for complex control architectures within the Symphony Plus and AC 800M ecosystems.
