CI830 CI840 communication interface can be redundant, new original ABB

Communication interface between the CI801 or CI840/ CI840A FCI and the TB820/ TB820V2/TB840/TB840A ModuleBus Modem of an I/O cluster or ABB drives units via the Optical ModuleBus. TB842 connects to CI801 via TB806 and to CI840/CI840A via TU847 and TB806 for single I/O or via TU846 and TB846 for redundant I/O.

Module termination unit (MTU) for redundant configuration of the field communication interface CI840/CI840A and redundant I/O. The MTU is a passive unit having connections for power supply, two electrical ModuleBuses, two CI840/ CI840A and two rotary switches for station address (0 to 99) settings.
