The ABB TU847 is a module termination unit (MTU) for the CI840/CI840A field communication interface. It is used to provide termination for the PROFIBUS DP or PA network cable and to connect the network to the CI840/CI840A. The TU847 is a key component of the ABB Ability™ System 800xA® distributed control system (DCS).
The TU847 supports both redundant and non-redundant configurations. In a redundant configuration, two TU847 units are used to provide a high level of availability and fault tolerance. If one TU847 unit fails, the other unit will take over and continue to communicate with the network.
The TU847 is a compact and rugged unit that is designed for industrial environments. It is easy to install and maintain, and it is compatible with a wide range of ABB products.
