Digital I/O expansion

The DBK210 signal conditioning and expansion board can be configured with up to32 isolated Grayhill 70M Series-­compatible
solid-state digital I/O modules. Four8-channel banks can be switch-­selected
as either inputs or outputs. The DBK210
features removable screw terminals forconvenient connection of field signals.
Also, each module location ­features an
LED to indicate channel status.

An on-board switch setting allows users
to determine the status of the digital­outputs in the event of the loss/recovery
of external power. When enabled, the lossof external power disables module ­outputs
until the application program writes newvalues to the data bus. When disabled, theBank 1

modules feature 250V isolation from thesystem (DaqBoard or Daq system) and fromother channels. A wide variety of solid-state
modules are available to sense AC and DC
signals and to switch AC and DC loads.

Up to 8 DBK210 boards can be daisy
chained (via multiple CA-37-x cables)­providing ­expansion up to 256 digital I/O­channels. Because of the DBK210’s onboard daisy-chain capability, only a single
cable is ­necessary from the host (DaqBoardor Daq system) to one of the DBK210s. For
applications with both ­analog and digital– Ch 16+Bank 3

I/O channel expansion requirements,
the DBK210 also has a P1 ­connector forattaching analog signals or expanding
with ­analog DBK options (such as theDBK207) when used with DaqBoard/2000
Series only.
The DBK210 ships with panel-mount
hardware and can also be either DIN-rail orrack-mounted with optional ­mounting kits.
