The OMB-DBK208 signal
conditioning and expansion
board can be configured with up
to 16 isolated Opto-22 compatible
solid-state relay (SSR) digital I/O
modules. Two 8-channel banks can
be jumper-selected as either inputs
or outputs. Each channel features
screw terminals for the convenient
connection of field signals, as well
as LEDs to indicate channel status.

Each user-configurable signal
conditioning module offers 500 V
isolation from the system and from
other channels. A wide variety
of SSR I/O modules are available
to sense AC and DC signals and
to switch AC and DC loads.

An on-board jumper (JP2) allows
users to determine the status
of the digital outputs in the event
of the loss/recovery of external
power. When enabled, the loss of
external power disables module
outputs until the application program
writes new values to the data bus.
When disabled, the loss of power
has no effect on the state or
continued control of the outputs.
Additionally, on-board logic disables
module outputs upon detection of
a CPU reset.

For the OMB-DAQBOARD-2000
Series boards, only a single
OMB-CA-195 cable is required
to terminate to the OMB-DBK208.
For applications with digital I/O only
channel expansion requirements,
up to 16 OMB-DBK208 boards
can be daisy-chained via multiple
OMB-CA-37-x cables, providing
expansion up to 256 digital I/O
channels.

For applications with both analog
and digital I/O channel expansion
requirements, the OMB-DBK203,
OMB-DBK206 and OMB-DBK209
expansion- adaptor boards are
available. All OMB-DBK signal
conditioning and expansion boards
are scanned at 5 µs/channel.
The OMB-DBK208 ships with
panel hardware; it can also be
rack-mounted with the optional
OMB-RACK3 rack
mount kit.
