Analog output
Introduction
Some DPM3 models include an analog output (4-20 mA).
The output is optoisolated with respect to the signal input and the power supply.
The meter provides a two terminal connector [(+ ) and (-)] that drives out a signal variation
from 4mA to 20mA proportional to a user-defined display range.
The signal can be used to transmit display information to a variety of terminal equipment such
as graphic recorders, controllers, remote displays or other devices that accept input data in
analog form.
The display values producing the full scale output (
OUT-HI
and
OUT-LO
) are introduced
via front-panel buttons in the same programming module. The analog output then follows the
display variation between the
HI
and
LO
programmed points.
The output signal can be set up for reverse action by programming the low display for the high
output (
OUT-HI
) and the high display for the low output (
OUT-LO
).
