Model PD690
4 1/2 Digit Universal Process Meter
Model PD690 is a high performance, easy to use,
industrial-grade
microprocessor digital process meter. It accepts all the standard
process
signals: 4-20 mA, 1-5 V, 0-5 V and 0-10 V and displays these signals in
engineering units on a 4 1/2 digit display. The display includes an
extra zero
which may be used to handle numbers up to 199,990.
- Easy Single Button Scaling with Lockout Feature
- 4-20 mA, 0-5 V, or 0-10 V Field Selectable Inputs
- 24
V Transmitter Power Supply Standard
- Stand Alone
Scaling
- Steady, Accurate Display to +/- 199,990
- 11 point Linearization
- Square Root
Extraction
- 4 1/2 Digit + Extra Zero
- NEMA
4X Front Panel
- 2 or 4 Relay = 4-20 mA Output
Options
Stand alone scaling allows the PD690 to
be scaled without applying an input.
Simply select internal calibration (I-CAL) mode and set desired display
for the
4mA and 20 mA value. To scale inputs such as 0 -5 V, 1-5V or 0-10V
without
applying a signal, first complete an initial calibration.
4 Visual Alarms Standard
- Front panel alarm status indication
- Perfect
for 'Visual indication only' applications
- any
combination of high or low set points
- 0-100%
dead-band adjustment
Big bright steady display for big
numbers
- 4 1/2 digit + extra zero display
- Displays
up to +/- 199,990
- 0.56" high efficiency red LED's
- Steady and quick responding display
Powers the loop
The 24 Volt transmitter power supply is standard on the PD690.
This feature
saves time and money by simplifying wiring and eliminating the cost of
an
external transmitter power supply.
NEMA 4X Front Panel
Wet, dirty and dusty environments don't bother the PD690's
NEMA 4X front
panel so it can be installed in almost any panel in the plant
Linearization
- The linearization feature has two modes of
operation:
- The 11 point user calibration
displays non-linear signals
- The square root
extraction displays the flow rate from a differential transmitter.
- 11 point user calibration
- input up to 11 calibration points
- perfect
for non-linear signals
Square Root Extraction
- Displays flow rates
- user
selectable low flow cutoff
- Only two calibration
points required
- accurate to +/- 0.1% FS +/- 1
count from 10-100% of flow
- The square root
extraction feature displays flow rate by extracting the square root of
a signal from a differential pressure transmitter. The user selectable
low flow cut off feature gives a reading of zero when the flow rate
drops below a user-set point.
NEW 18-36 Vdc
POWERED
The PD690 Universal Process Meter can now be powered from
18-86 Vdc. This new
option provides up to 500 Vdc of isolation. All the features and
options
available on the AC powered meters are available on the DC powered
meters.
Note: 18-86 VDC powered PD690's are not UL listed.
Remember
Every PD690 comes with 4 visual alarms standard! The PD690
universal process
meter can be equipped with 2 or 4 relay contacts and a isolated 4-20 mA
transmitter output. These options may be combined in any configuration
to
satisfy a wide variety of applications. A fully loaded model PD690-3
includes 4
relays and a isolated 4-20 mA transmitter output.
Two or four Relays
