NEW ABB S800 I/O Module Termination Unit (MTU) TU846 3BSE022460R1 for Module CI840A
Description of TU846
The TU846 is a 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.
A ModuleBus Optical Port TB842 can be connected to TU846 via TB846.
Four mechanical keys, two for each position, are used to configured
the MTU for the right types of modules. Each key has six positions,
which gives a total number of 36 different configurations.
Module Termination Unit for dual CI840/CI840A, redundant I/O. TU846
are used with redundant I/O modules and TU847 with single I/O
modules. The maximum ModuleBus length from the TU846 to the
ModuleBus terminator is 2.5 meters. TU846/TU847 needs space to the
left in order to be removed. Cannot be replaced with power applied.
