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. 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. 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. 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. |
