28 VDC Mode. The primary purpose of the 28 VDC mode is to provide power for external loop
transmitters. The hookup is simple, as shown below.
Another use of the 28 VDC mode is to provide excitation for bridge-type sensors, such as load cells
(strain gages).
The primary purpose of the 28 VDC mode is to power external user-supplied loop transmitters. The
hookup is simple, as shown below. A DIN5 connector allows easy connection of lead wires.
The 28 VDC mode can also be used to provide a 14 VDC excitation source for bridge-type sensors such as
load cells (strain gages). The excitation voltage is not regulated by the DBK30A; so, this voltage must be
externally regulated to 10.00 V for most load cells.
Excitation voltage from DBK30A is not regulated by the unit, and must therefore be
regulated externally. For most load cells, excitation voltage should be regulated to 10 V.
