Expansion and Terminal Panel Connection DBKs
The following DBKs offer provide various expansion and connection options. The stackable 3-slot
DBK10 low-profile enclosure can be used for up to three DBKs. If a system has more than 3 DBKs, the
10-slot DBK41 can be used. Several DBK41s can be daisy-chained to accommodate many DBKs in one
system.

Power Supply DBKs
Power supply type DBKs are typically used in laboratory, automotive, and field applications. Input power
can come from any +10 to +20 VDC source, or from an AC source by using an appropriately rated AC-to-
DC adapter. The DBK30A rechargeable power supply can power DBK modules where AC mains are not
available (the DBK30A outputs 28 V for powering transducers). For a large number of DBK cards, the
DBK32A or DBK33 can be installed into an expansion slot. The DBK33 is used when +5 V is required in
addition to ±15 VDC. The DBK34 provides a steady 12 or 24 VDC while working with vehicle electrical
systems that may be turned on or off during testing.

Tips on Setting up a Data Acquisition System
A successful installation involves setting up equipment and setting software parameters. In addition to this
manual, you may need to consult your Daq device or LogBook user’s manual.
DBKs should be configured before connections are made and power is applied. This sequence can prevent
equipment damage and will help ensure proper operation on startup. Many DBKs have on-board jumpers
and/or DIP switches that are used for setting channels and other variables. You will need to refer to the
individual DBK document modules to ensure that the DBKs are properly configured for you application.
Prior to designing or setting up a custom data acquisition system, you should review the following tips.
After reviewing the material you can write out the steps to setup a system that will best meet your specific
application needs.
