Each OMB-DBK15 multiplexing input
card provides sixteen channels of
current or voltage input to OMEGA’s
OMB-LOGBOOK and OMB-DAQBOARD-2000 Series data acquisition
systems. An OMB-LOGBOOK and OMB-DAQBOARD-2000 Series
can accept up to 16 OMB-DBK15
cards, for a total of 256 potential
analog input channels per system.
The OMB-DBK15 features a
16-channel multiplexer and a
programmable gain input amplifier.
Its durable component sockets
accept resistors that configure each
channel for either current-to-voltage
conversion or for voltage attenuation.
The OMB-DBK15 is supplied with
sixteen precision 250 ohm resistors
for making 4 to 20 mA measurements,
and sixteen sets of 6:1 voltage
dividers for accommodating up to
±30 V* inputs. (* ±10 V to 30 V input signals can be
measured by installing attenuation
resistors on the card)
The OMB-DBK15 can also accept
other, user-supplied resistor values,
facilitating user-selectable current-to-
voltage conversion or voltage
attenuation factors.
When employed without resistors,
the OMB-DBK15 provides sixteen
differential voltage inputs, which
accommodate ±5 V full scale inputs.
The OMB-DBK15’s input amplifier is
software programmable for x1 or x2
gain per channel, and for unipolar 0
to +10 V or bipolar -5 to +5 V input
per channel.
Voltage Measurements. The
OMB-DBK15 accommodates voltage
measurements beyond the standard
10 V range, accepting voltage divider
resistors for up to ±30* VFS inputs.
You can obtain any combination of
input ranges by simply installing the
appropriate resistor combination on
the OMB-DBK15 card. The card’s
on-board programmable gain
instrumentation amplifier (PGIA)
can be set for a ±5 V output span or
a 0 to +10 V output span, allowing
users to set the OMB-LOGBOOK
or OMB-DAQBOARD-2000 Series for
either configuration.
Current Measurements.
The OMB-DBK15 is ideal for
accommodating transducers with
4 to 20 mA output; one need only
install the 250 ohm resistors provided
in the appropriate location on the
board.
