Function Module termination unit (MTU)
for single configuration of
Optical ModuleBus Modem
TB840/TB840A. The MTU is a
passive unit having connections
for power supply, a single
electrical ModuleBus, one
TB840/TB840A and a rotary
switch for cluster address
(1 to 7) setting.
Module termination unit (MTU)
for redundant configuration
of Optical ModuleBus Modem
TB840/TB840A. The MTU is a
passive unit having connections
for power supply, double
electrical ModuleBus, two
TB840/TB840A and a rotary
switch for cluster address
(1 to 7) setting.
Module termination unit (MTU)
for redundant configuration
of Optical ModuleBus Modem
TB840/TB840A, for use with
non-redundant I/O. The MTU
is a passive unit having
connections for power supply,
a single electrical ModuleBus,
two TB840/TB840A and a
rotary switch for cluster
address (1 to 7) setting.
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.
