The DIN5 is the system's basic power connector (see the following figure). The CA-115 is a 6-in. cable
with a plug (male) DIN5 connector on both ends. The CA-115 is used to connect DBK32As [or
DBK33s] in parallel when they are to be powered by the same power supply.
DIN5 connectors for LogBook, DBK34, and DBK34A have threaded retaining rings.

Note:
The following figure shows the pinout for the DBK34 and DBK34A Power Out DIN5
connector. The 28 V pin is only active when the device is in the 28 VDC mode;
however, the 14 V pin is active regardless of the mode selected.
An Introduction to Power-Related DBKs
The power-related DBK options are the DBK30A, DBK32A, DBK33, DBK34, and DBK34A. From the
standpoint of providing reliable power, these DBKs have proven convenient in laboratory, automotive, and
field applications.
Input power for these devices can come from any 10 to 20 VDC source, or from an AC source via an
appropriate AC-to-DC adapter.
A brief synopsis of the DBK power options follows. Refer to the respective document modules for
complete information.
DBK30A
The DBK30A's 28 V output will power 4 to 20 mA transducers.
power DBK modules in situations where AC mains are not available.
Note: Some transducers (e.g., 2-wire 4-20 mA transmitters, bridge-configured sensors, etc) require an
excitation voltage in order to work properly. The DBK30A supplies 14 and 28 VDC. Consult
transducer documentation before applying power.
