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.

Overview

The DBK81, DBK82, and DBK83 are used in temperature measurement applications that make use of

thermocouples. The DBK81 provides connections for 7 thermocouples. Both the DBK82 and the DBK83

provide connections for 14 thermocouples. The two 14 channel cards differ from each other in that the

input connectors of the DBK82 are on the board, but connectors of the DBK83 are located in an external

connection pod.

All three cards feature on-board cold junction compensation (CJC) for direct measurement of type J, K, T,

E, N28, N14, S, R, and B thermocouples. The following table provides the temperature range for each of

these thermocouple types.

The three DBK cards connect to external thermocouples via channels, as follows:

• DBK81 – up to seven thermocouples can be connected, using channels 1 through 7, inclusive

• DBK82 and DBK83 - up to fourteen thermocouples can be connected, using channels

1 through 7 for the first seven and channels 9 through 15 for the second set of seven.

Note: On the DBK81, there is one CJC. It is measured on channel 0. On the DBK82 and DBK83 there

are two CJCs, measured on channels 0 and 8.

In addition to thermocouple measurements, each input channel can be configured for a fixed voltage gain

of 100. When in this mode, voltage can be measured in the range of ±100 mV, or ±50 mV, depending on

the type of Daq device being used.

Up to sixteen DBK81, DBK82, or DBK83 cards can be attached to a single LogBook or Daq device,

providing up to 224 temperature channels. The cards need not be the same. For example, you could have

ten DBK81 cards, three DBK82 cards, and three DBK83 cards in one system.
