ABB Digital S800 I/O Module Termination Unit DCS TU849 3BSE042560R1
In Stock
Description of TU849
The TU849 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, a single electrical ModuleBus, two
TB840/TB840A and a rotary switch for cluster address (1 to 7)
setting.
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. The
configurations can be changed with a screwdriver.
The MTU can be mounted on a standard DIN rail. It has a mechanical
latch that locks the MTU to the DIN rail. The latch can be
locked/unlocked 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.
