MODEL PAX2A – 1/8 DIN ANALOG PANEL METER
DESCRIPTION
The PAX2A Analog Panel Meter offers many features and performance
capabilities to suit a wide range of industrial applications. The PAX2A has a
universal input to handle various input signals including DC Voltage/Current,
Process, Resistance and Temperature. The optional plug-in output cards allow
the opportunity to configure the meter for present applications, while providing
easy upgrades for future needs. The PAX2A employs a dual line, tri color
display with a large 0.71", tri color 6 digit top display line and a 0.35", 9 digit
green bottom display line.
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 or calculate service
intervals of motors, pumps, etc. The meters have up to 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. These
include RS232, RS485, DeviceNet, and Profibus-DP. The PAX2A can be
programmed to utilize ModBus protocol. With ModBus, the user has access to
most configuration parameters. 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.
The PAX2A includes a built-in USB programming port that makes it possible
to configure the meter using a Windows
communication option cards. The configuration data can be saved to a file for
later recall.

CONFIGURATION WITH CRIMSON PROGRAMMING SOFTWARE
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 or min readings.
Once the meters have been initially configured, the parameter list may be locked
out from further modification in its entirety or partially locked allowing the
setpoint values to remain accessible.
The meters have been specifically designed for harsh industrial environments.
With NEMA 4X/IP65 sealed bezel and extensive testing of noise effects and 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.

The PAX2A supports both the RLC protocol and also supports ModBus communications using the standard RS232 and RS485 Pax option cards. The Pax ModBus option card should not be used with the PAX2A, as the PAX2A internal ModBus protocol supports complete unit configuration, and is much more responsive.
