channel with the highest or lowest
reading, process deviation from a
pre-programmed setpoint, and
display differentials between
channels. The DPS3300 can also
run merely as a timer.

Additional features include min/max
readings and rate of change for all
channels. A control relay or
open-collector output for each
channel is available as an option. A
built-in buzzer (available with output
option) sounds an alarm whenever
a limit is reached. Visual indication
of relay output status is given
by LEDs.

automatically scans each channel,
displaying the channel number and
its process reading.

Signals from thermocouples, RTDs,
and thermistors are linearized and
can be displayed in °C or °F.
Current, voltage, and millivolt
signals are easily scaled for
indicating the process in specified
engineering units. Up to 7 different
processes can be displayed on a
single scanner, and each channel
can be assigned a 3-digit,
alphanumeric engineering unit
(psi, ft, etc.). Channels are
sequentially displayed for a
programmed length of time; with the
hold feature, the display can be held
indefinitely on any one channel.

The DPS3300 has multiple display
modes and can be programmed to
scan all channels, display the

Housed in a wall-mount, watertight
plastic enclosure, the DPS3300
Series scanners offer highly
functional multichannel scanning
with a number of very useful
features. Tasks that formerly
required multiple monitors can now
be accomplished by using a single
unit. Signals from 7 different
transducers are carried into
conveniently located screw
terminals that are accessed through
a sealed plastic cover. The unit
