4 1/2 Digit Universal Process Meter
Model PD690 is a high performance, easy to use,
microprocessor digital process meter. It accepts all the standard
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
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
V Transmitter Power Supply Standard
- Stand Alone
- Steady, Accurate Display to +/- 199,990
- 11 point Linearization
- Square Root
- 4 1/2 Digit + Extra Zero
4X Front Panel
- 2 or 4 Relay = 4-20 mA Output
Stand alone scaling allows the PD690 to
be scaled without applying an input.
Simply select internal calibration (I-CAL) mode and set desired display
4mA and 20 mA value. To scale inputs such as 0 -5 V, 1-5V or 0-10V
applying a signal, first complete an initial calibration.
4 Visual Alarms Standard
- Front panel alarm status indication
for 'Visual indication only' applications
combination of high or low set points

- 4 1/2 digit + extra zero display
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.
saves time and money by simplifying wiring and eliminating the cost of
external transmitter power supply.

- 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
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
available on the AC powered meters are available on the DC powered
Note: 18-86 VDC powered PD690's are not UL listed.
Every PD690 comes with 4 visual alarms standard! The PD690
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
satisfy a wide variety of applications. A fully loaded model PD690-3
