Detailed data
ABB TU848 3BSE042558R1 Module Termination Unit
The TU848 is a module termination unit (MTU) for redundant configuration of Optical ModuleBus Modem TB840/TB840A.The MTU is a passive unit having connections for double power supply (one for each modem), double electrical ModuleBus, two TB840/TB840A and a rotary switch for cluster address (1 to 7) setting.
Two mechanical keys 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. The configurations can be changed with a screwdriver.Termination unit TU848 has individual power supply connections and connects TB840/TB840A to redundant I/O. Termination unit TU849 has individual power supply connections and connects TB840/TB840A to non-redundant I/O.
TU848 uses screw terminals for wiring. This allows field devices to be connected easily and safely. It can handle various signal types, such as digital or analog signals.
