The OMB-DBK42 sixteen-slot
OM5 signal conditioning module
allows OMEGA’s OMB-LOGBOOK
or OMB-DAQBOARD-2000 Series
data acquisition systems to
accom-modate any combination
of up to sixteen OM5 input signal
conditioning modules*. Each user-installable
signal conditioning
module offers 500 V isolation from
the system and from other channels.
A single cable connects the
OMB-DBK42’s output to your
data acquisition device. One OMB-LOGBOOK
or OMB-DAQBOARD-2000
Series module can support up to sixteen OMB-DBK42 units,
providing a total of 256 isolated
analog input channels.
Powering the OMB-DBK42
The OMB-DBK42 can obtain its
input power from a number of
sources: an included AC adaptor,
an optional OMB-DBK30A
rechargeable battery/ excitation
module, or directly from a 12 Vdc
source, such as an automobile
battery. The OMB-DBK42 has a
built-in DC/DC converter capable of
powering a full complement of OM5
modules even when the unit is fully
outfitted with strain gage modules with
bridge excitation on every channel.
Signal Connections
The optional OMB-CN-71 and
OMB-CN-72 signal connection
blocks provide a convenient way
of connecting analog signals to the
OMB-DBK42. The OMB-CN-71
connection block is for
non-thermocouple applications, while the OMB-CN-72, which features
cold-junction sensors, is for
thermocouple applications. Each
block contains 4 terminals per
channel, providing access to both
the OM5 modules’ input and
excitation output features.
