The OMB-DBK24 has been discontinued. Please contact our Data Acquisition Engineering department.
The OMB-DBK24 is a 24-line digital-output
module that provides isolated
digital outputs for OMEGA’s
OMB-LOGBOOK and
OMB-DAQBOARD-2000 Series data
acquisition systems. The OMB-DBK24
provides 500 V of channel-to-channel
and 500 V of channel-to-system optical
isolation for complete system protection.
This isolation protects the data
acquisition system from damage caused
by accidental contact with high external
voltages and eliminates troublesome
ground loops. Up to eight OMB-DBK24
modules can be connected to one
system, for a total of 192 digital outputs.
Connections
The OMB-DBK24 connects to a system’s
P2 digital I/O connectors and uses the
existing digital I/O lines as a
communications bus. Thus, the lines on a
system’s digital I/O connectors are not
user accessible when an OMB-DBK24 is
in use. The OMB-DBK24 can be daisy-chained
with other OMB-DBK digital I/O
cards or modules via optional expansion
cables. Signal connections to the OMB-DBK24
are made via screw terminals,
which are conveniently located on its
slide-out PC board. Power-On-Reset
The module features a power-on-reset
function, allowing users to set the
outputs to either “on” or “off” prior to
start-up. Each power up output state is
determined by dip-switch settings prior
to the first write command to the
module. Power
The OMB-DBK24 is equipped with an
internal power supply and external AC
adaptor. It can also be powered from an
OMB-DBK30A battery module, a 12 V
car battery, or from any 9 to 24 Vdc
source.
