DBK207 and DBK207/CJC

The DBK207 and DBK207/CJC are carrier boards for 5B-compatible analog input modules. They

each provide:

•

two P1 connectors – for ANALOG I/O

•

a 5 VDC power terminal

•

footprints for sixteen 5B Modules

•

16 terminal blocks.

In addition, DBK207/CJC provides Cold Junction Compensation. The DBK207 and DBK207/CJC

each include a 100-pin P4 connector for use with DaqBoard/2000 Series and cPCI DaqBoard/2000c

Series Boards.

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.

DBK207 and DBK207/CJC are typically installed in NEMA-type panels; however, they may 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).

DBK207 and DBK207/CJC allow Daq-based acquisition systems to use various combinations of sixteen

5B signal-conditioning modules. 5B modules can accommodate a variety of signals, including low-level

thermocouple and strain-gage signals. Configuration options are flexible. You can select the type of signal

attached to each channel. One Daq device can support up to 16 DBK207 [or DBK207/CJC] boards,

providing a maximum of 256 isolated, analog input channels. Note that Daq devices scan the channels at

the same 10 µs/channel rate as other DBKs (256 scans in 2.56 ms in a full system).

Each user-installed 5B module offers 500 V isolation from the system and between channels. Both

DBK207 and DBK207/CJC include 16 screw-terminal blocks for signal inputs. In addition, the

DBK207/CJC includes cold junction compensators (CJCs) for use with thermocouple 5B modules.

Sockets are provided for user-installed AC1362 current-sense resistor modules, as discussed in

5B Module Connection in the DBK207 section of the DBK Option Cards and Modules User’s Manual

(p/n 457-0905).
