Reference Notes:

o Chapter 2 includes pinouts for P1, P2, P3, and P4. Refer to pinouts applicable to your

system, as needed.

o In regard to calculating system power requirements, refer to DBK Basics located near

the front of this manual.

Reference Note:

Users of the DBK44 signal-conditioning card may be interested in the DBK207 and DBK207/CJC,

Carrier Boards for 5B Compatible Analog I/O Modules. Each DBK207 and DBK207/CJC board

includes a 100-pin P4 connector for DaqBoard/2000 Series and /2000c Series compatibility, two P1

connectors for analog expansion, a power connection terminal, and 16 signal terminal blocks. In

addition, the DBK207/CJC board includes CJC (Cold Junction Compensation) for thermocouple

applications. DBK207 and DBK207/CJC can be mounted in Nema-type panels.

Overview

The 2-channel DBK44 allows LogBook or Daq device systems to use any combination of 5B signal-

conditioning modules. 5B modules can accommodate a variety of signals (low-level thermocouple signals

to strain-gage signals, etc). Configuration options are flexible. You can select the type of signal attached

to each channel. One LogBook or Daq device can support up to 128 DBK44 cards, providing up to 256

isolated, analog input channels.
