Feedback bridges
Cable wire colors (HBM transducer):
rd = red; wh= white; bk= black; bu= blue Cable shields on
connector housing
Fig. 5.4 4-wire connection
For 4-wire transducers, you need to solder feedback bridges (shorting bars) for the sense
leads into the transducer plug. If you need an extension, make it in a 6-wire configura­
tion. Connect the cable shields extensively to the connector housing.
X3, power supply connection
The DSE has an 4-pin M12 plug (T-coded) for connecting the power supply. This is
located in the middle on the back, and is labeled X3 ([4] in Fig. 5.1). Note that the
operating voltage may be between 15 V
DC
and a maximum of 30 V
DC
. The nominal
(rated) voltage is 24 V
DC
. The pin assignment is shown in Fig. 5.5.
