The OMB-DBK30A, $649, rechargeable battery/excitation module,
shown smaller than actual size
⻬ Provides up to Six
Hours of Operation
for Portable Data
Acquisition
⻬ 28 Vdc Excitation
Output for Applications
Such as 4 to 20 mA
Transducers Biasing
The OMB-DBK30A
rechargeable nickel-cadmium
battery/excitation module enables
OMEGA’s OMB-LOGBOOK and
OMB-DAQBOOK-2000 Series
acquisition systems to be used
in remote or portable applications.
Housed in a metal enclosure of the
same size as these portable data
acquisition systems, the unit
includes durable, Velcro-style
tabs for easy attachment under
these units.
The OMB-DBK30A has two operating
modes. In one mode, it provides a
14 Vdc output capable of operating
one of the above-mentioned systems
for three to six hours.
In the second mode, it provides an
additional 28 Vdc output, referenced
to system common, that can be
used to provide excitation for 2-wire
or 4 to 20 mA transducers. At the
same time, the 14 V output can
power OMEGA’s portable data
acquisition systems for up to
three hours.
An internal switch allows the user
to con-figure the OMB-DBK30A
as needed.
The OMB-DBK30A has two
battery packs, each with its own
peak termination charging circuit.
The unit features a charge-status
LED that indicates charging and
full-charge status, and also provides
a power-out LED that indicates
external loading. The unit includes
an AC adaptor for recharging.
Packaging
You can stack the OMB-DBK30A
beneath an OMB-LOGBOOK or
OMB-DAQBOOK-2000 Series
portable data acquisition module,
both of which are available with an
optional screw-in handle.
The result is a compact and
securely connected data acquisition
system that you can conveniently
carry from one application site to
another.
