The DP470 Series of single- and
multiple-input digital temperature
and process indicators sets a
standard for performance, features,
value, and reliability. With built-in
digital programmability,
communications, and powerful
Windows-based software, the
DP470 is ideal for monitoring,

⁄8 DIN

testing, and process-control
applications. Complete configuration
of the instrument can be quickly
performed from the front panel,
including designating sensor input
type, sampling rate, limit settings,
and resolution. Display of process
and min/max values is also user
selectable from the front panel. The
standard single-input model features
easy-to-use front-panel configuration
and display of temperature or
process measurement with either

0.1 or 1° resolution, min/max values,
and limit conditions.

Windows-Based RS232
Communications Software

The DP470 is far more than a
stand-alone, high-performance
digital temperature or process
indicator. Thanks to the exclusive
DP470 software, the DP470 is a
powerful real-time data monitoring,
control, and data logging system.
Clear, menu-driven displays guide
the user through instrument setup
and allow the monitoring, collection,
and logging of data remotely through
a PC serial port. Software alarms,
channel ID, and min/max values are
presented, along with a simulated
LED display of the selected channel,
in an on-screen control panel format.
In addition, data can be exported as
text to create graphs and print
hard-copy reports. (No Protocol is

available).

Multiple Inputs

With the multiple-input model
installed, the DP470 Series can
monitor up to 6 thermocouple or
process inputs or 3 RTD channels.
On single-input models, an optional
board can be installed. This board
provides enhanced alarm functions
as well as a scalable 4 to 20 mA/0 to
10V analog output.

All active inputs can be manually
selected or automatically scanned.
A front-panel channel indicator
accompanies the displayed data.
Individual limits can be assigned to
each channel. A built-in 5 A rated
form “C” relay is energized
whenever the limit on the selected
channel is exceeded.

Dual Alarms

With the dual-alarm model, the DP470
can be configured to perform on/off
control functions as well as process
monitoring. Setpoints can be set for
high, low, or deviation. In addition,
hysteresis (deadband) and delay can
be programmed into each setpoint.
Alarm conditions can be programmed
for manual acknowledgment or for
automatic reset. The dual-alarm option
comes equipped with two 5 A rated
form “C” (SPDT) relays, one for each
alarm setpoint. A flashing display
alerts the user to an alarm condition.

Analog Output Models

Extended Warranty

Program

SM

Analog output capability is also
available in combination with the dual
alarm option. A linearized output
(4 to 20 mA or 0 to 10V) with fully
adjustable zero and span allows the
instrument to serve as an indicating
transmitter, or as a high-level input to
a PC-based converter or other
recording device.
