DBK210, pg. 2 987594 DBK Option Cards and Modules
DBK210 is a four-bank carrier board for optically-isolated Grayhill 70M-Series mini-modules. Each bank
supports up to eight digital I/O modules. Each bank can be independently set to input or output. The
settings are made via micro-switches on S1 (see next two figures). The Grayhill 70M-Series I/O modules
are industry standard, 5-volt logic level modules.
WARNING
Ensure that hard-wire emergency over-ride circuitry exists for all applications that
make use of dangerous switch-loads. Do not operate such switch-loads unless
emergency over-ride circuitry is present.
Note 1: DBK210 is not used with DaqBoard/2003.
Note 2: DBK210 can be used with DaqBook/200 series and Daqboard/200 series devices;
but should not be used with DaqBook/100 series or DaqBoard/100 series devices.

S1 Detail
The S1 settings for the Banks and the Local Addresses must match the associated settings
in DaqView. This is explained in the Software Setup section, which begins on page 7.
Note: S1 functionality is explained in the following three sections: External Power Watchdog (pg. 5),
Setting Module Banks to Input or Output (pg. 5), and Setting the Local Addresses (pg. 6).
