Overview
The DBK65 is an 8 channel transducer
interface module. Transducers of 2, 3, 4,
and 6 wire type can be easily connected
to the device by means of removable
screw terminal blocks, 1 per channel.
The module is ideally suited for
transducer outputs of the following
types. Wiring schematics are provided
on page 2 of this DBK65 section.

4-wire bridge based transducers
6-wire bridge based transducers
DBK65 Block Diagram
Note 1: The user can install a resistor for use with the programmable regulator. The programmable voltage source can be
within the range of 5 to 20 VDC.
Note 2: The user can install a 250resistor across the positive and negative signal lines (+Signal and -Signal) for
4 to 20 mA transducer outputs.
