GENERAL DESCRIPTION
The PAXDP Dual Process Input Meter offers many features and performance
capabilities to suit a wide range of industrial applications. Available in two
models, AC or DC power, the meter has the capability to accept two, 4 to 20 mA
or 0 to 10 VDC input signals. Each input signal can be independently scaled and
displayed. In addition, a math function can be performed on the two signals, C +
A + B, C - A - B, C + A - B, AB / C, CA / B, or C (A / B - 1). Any of the three
meter values can have Alarms, Comms, and/or a Retransmitted Analog Output
capability by simply adding optional cards. The optional plug-in output cards
allow the opportunity to configure the meter for current applications, while
providing easy upgrades for future needs.
The update rate of the meter is user selectable. This will help in those
applications where a quick response from the meter is of the utmost importance.
The rate can be adjusted from eight selections with a minimum of 5 updates/
second to a maximum of 105 updates/second.
The meters employ a bright 0.56" (14.2 mm) red sunlight readable LED
display. The intensity of display can be adjusted from dark room applications up
to sunlight readable, making it ideal for viewing in bright light applications.
The meters provide a MAX and MIN reading memory with programmable
capture time. The capture time is used to prevent detection of false max or min
readings which may occur during start-up or unusual process events.
The signal totalizer (integrator) can be used to compute a time-input product.
This can be used to provide a readout of totalized flow, calculate service intervals
of motors or pumps, etc. The totalizer can also accumulate batch operations.
The meter has four setpoint outputs, implemented on Plug-in option cards.
The Plug-in cards provide dual FORM-C relays (5A), quad FORM-A (3A), or
either quad sinking or quad sourcing open collector logic outputs. The setpoint
alarms can be configured to suit a variety of control and alarm requirements.
Communication and Bus Capabilities are also available as option cards. The
standard output is in Modbus Protocol. Any of the following option cards,
RS232, RS485, DeviceNet, or Profibus can be used with the meter. Readout

values and setpoint alarm values can be controlled through the bus. Additionally,
the meters have a feature that allows a remote computer to directly control the
outputs of the meter.
A linear DC output signal is available as an optional Plug-in card. The card
provides either 20 mA or 10 V signals. The output can be scaled independent of
the input range and can track either the input, totalizer, max/min readings, or
math calculation value.
Once the meters have been initially configured, the parameter list may be
locked out from further modification in its entirety or only the setpoint values
can be made accessible.
The meters have been specifically designed for harsh industrial environments.
With NEMA 4X/IP65 sealed bezel and extensive testing of noise effects to CE
requirements, the meter provides a tough yet reliable application solution.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in this
literature or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other actuators
not equipped with safeguards. To do so can be potentially harmful to persons or
equipment in the event of a fault to the unit.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
