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: DBK208 is not used with DaqBoard/2003.
Note 2: DBK208 can be used with DaqBook/200 and Daqboard/200 (ISA-type) series devices;
but should not be used with DaqBook/100 or DaqBoard/100 (ISA-type) series devices.
DBK208 Block Diagram
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).
DBK208 is controlled digitally from the Daq device (DaqBook or DaqBoard) through one of two
connectors, as follows:
DaqBook/200 Series Devices – control is through the 37-pin P2 digital port of the DaqBook and one of two DBK208
P2 connectors.
DaqBoard/200 Series boards [ISA-type] - control is through the 37-pin P2 digital port of the DaqBoard and one of
the DBK208 P2 connectors.
DaqBook/2000 Series Devices, DaqBoard/2000 Series boards, and cPCI 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 2000 series board’s 100-pin P4 connector to a DBK208’s P4
connector via a CA-195 cable.
Indirect connection can be made using one of the DBK200 Series P4-adapters that includes a 37-pin P2
connector (DBK201, DBK202, DBK203, DBK204, DBK206, DBK209, or another DBK208). CA-37
cables are used to connect from P2 to P2.
