2. Product Description
2.1 General Function
The TU847 3BSE022462R1 is a Module Termination Unit (MTU) specifically designed for the redundant configuration of the field communication interface CI840/CI840A. It serves as a crucial link in industrial automation setups, enabling seamless communication and power distribution among various components. As a passive unit, it plays a pivotal role in establishing connections for power supply, the electrical module bus, two CI840/CI840A units, and incorporates two rotary switches for setting the station address within the range of 0 to 99. Additionally, it allows for the connection of a Module Bus optical port TB842 via TB806, expanding the communication capabilities within the system.
2.2 Key Features
- Mechanical Key Configuration: Four mechanical keys, with two keys for each position, are utilized to configure the MTU for the appropriate types of modules. Each key offers six positions, resulting in a comprehensive total of 36 different configuration options. This mechanical keying system provides a reliable and precise way to ensure that the correct module types are installed, preventing incorrect module insertions that could lead to system malfunctions.
