Description

The DBK48 module can accommodate up to sixteen 8B isolated-input signal-conditioning modules for use

with Daq systems. A single cable connects the DBK48 output to the P1 analog input connector on the

primary device. One Daq system can support up to 16 DBK48 modules, providing a total of 256 isolated

analog input channels. The A/D converter scans the DBK48 channels at the same 5 µs/channel rate that it

scans all other channels from DBK series analog expansion and signal conditioning cards.

Other features of DBK48 include:

• Built-in power supply that operates from 10 to 30 VDC and can power a full complement of

8B modules (even with bridge excitation).

• Removable, plug-in screw-terminal blocks for convenient connection of 8B modules.

• On-board cold-junction sensing for thermocouple 8B modules.

• For each 8B module, 250 V isolation from the system and from other channels.

Note 1: Only channels 0, 2, 4, 6, 8, 10, 12, and 14 can be connected

to excitation. For example, in the above block diagram

Channel 0 could be connected to Excitation; Channel 1

could not.

Note 2: Each channel can accept a plug-in resistor to serve as a

current shunt. In the above diagram, Channel 0 has a

current shunt installed, Channel 1 does not. Only current-

input type modules require the plug-in resistors. The plug-in

resistors must be removed for all other module types.
