DBK208
DBK208 is a two-bank carrier board for optically-isolated Solid-State-Relay (SSR) modules. Each
bank supports up to eight digital I/O modules. The banks can be independently set as “input” or
“output” via jumpers (JP0 for Bank 0, and JP1 for Bank 1). The I/O modules are industry standard
Opto-22 compatible, 5-volt logic level modules.
The DBK208 provides:
•
•
•
two P2 connectors for DIGITAL I/O
footprints for sixteen optically-isolated Solid-State-Relay (SSR) Modules
16 dual-screw terminal blocks.
DBK208 includes a 100-pin P4 connector for use with DaqBoard/2000 Series and /2000c Series
Boards.

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: DBK208 is not used with DaqBoard/2003.
DBK208 boards are typically installed in NEMA-type panels; however, they may alternatively be installed
on DIN rails. Separate mounting instructions are included with Rack Mount Kit (part no. Rack-DBK-3)
and with DIN-rail Mount Kit (part no. DIN-DBK-1).
In regard to the DaqBoard/2000 Series and DaqBoard/2000c Series boards, control originates in the
board’s 100-pin P4 connector. Connection of these boards to DBK208 can be made directly or indirectly
as follows:
• Direct connection can be made from the DaqBoard/2000 Series or /2000c Series board’s
100-pin P4 connector to a DBK208’s P4 connector via a CA-195 cable.
• Indirect connection can be made using an additional DBK200 Series P4-adapter that includes
a 37-pin P2 connector. For example, one of the following could be used: DBK201, DBK202,
DBK203, DBK204, DBK206, DBK209, or another DBK208. CA-37 cables are used to
connect from P2 to P2.
Note that a single Daq-based data acquisition system can support up to 16 DBK208 boards, providing a
total of 256 channels. DBK208 boards contain two DB37 P2 connectors for the purpose of daisy-chaining
to other DBK208s or to other P2-supported devices.
