3.3 DC power connection
Models configured for DC power (899-10-230-32) are provided with a terminal labeled P+
and are wired as shown in Figure 3-9. Models configured for battery power
(899-10-230-30) may optionally be connected to DC power and the battery will function
as backup power when DC is lost. The same power supply may be used to power other
circuits including a PNP-type sensor. However to maintain input isolation, a separate
power supply must be used to power the isolated 4-20 mA transmitter as shown in
Figure 3-10 and/or to power the Opto-Isolated Flowmeter as shown in the figure below.
