1. General Introduction
The TU847 is a module termination unit (MTU) for redundant configuration of the field communication interface CI840/CI840A. The MTU is a passive unit having connections for power supply, electrical Module Bus, two CI840/CI840A and two rotary switches for station address (0 to 99) settings. A Module Bus Optical Port TB842 can be connected to TU847 via TB806.
Four mechanical keys, two for each position, are used to configure the MTU for the right types of modules. Each key has six positions, which gives a total number of 36 different configurations. TU846/TU847 needs space to the left in order to be removed. Cannot be replaced with power applied. TU847 is also available in a G3 compliant version (TU847Z).
