Overview
The ABB TU845 3BSE021447R1 Redundant Termination Unit is a robust solution designed for industrial automation applications. Supporting up to 8 I/O channels alongside 2+2 process voltage connections, this unit ensures flexibility and reliable performance in demanding environments. Each channel offers two I/O connections and one ZP connection, making it versatile for various input and output configurations.
Functional Highlights
This termination unit is capable of handling a maximum rated voltage of 50 V and a current capacity of 2 A per channel. The TU845 effectively manages the distribution of two ModuleBuses—one for each connected I/O module and one for cascading to the next MTU in the network. By shifting outgoing position signals, it generates the correct addresses for I/O modules, ensuring smooth communication across the system.
Installation is straightforward, as the TU845 features a mechanical latch that secures it firmly to a DIN rail. Furthermore, to accommodate different I/O module types, the unit includes four mechanical keys, allowing for a total of 36 different configuration options. This flexibility makes the TU845 highly adaptable to a wide range of industrial applications.
