DESCRIPTION
The PAX2S Strain Gage Panel Meter offers many features and performance
capabilities to suit a wide range of industrial applications. The PAX2S has a
strain gage input to handle various types of bridge configurations including load
cell, pressure and torque sensors. The optional plug-in output cards allow the
opportunity to configure the meter for present applications, while providing easy
upgrades for future needs.
Highlighting the PAX2S is a dual line, display with a large 0.71", tri-color 6
digit top display line and a 0.35", 9 digit green bottom display line. The meter
also offers programmable units display, providing capability to tag the display
with units of measure. Display color change capability provides machine
operators a visual display of changing conditions, even when the operator is not
close enough to read the actual display value. In addition, a universal power
supply provides the ultimate in flexibility for both AC and DC power.
The meter provides 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 weight or calculate service intervals of
motors, pumps, etc.
The meter has up to four setpoint outputs, implemented on plug-in option
cards. The plug-in cards provide dual FORM-C relays, quad FORM-A, 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.
The PAX2 can be programmed to utilize Modbus protocol. With Modbus, the
user has access to all configuration parameters. Readout values and setpoint
alarm values can be controlled through the bus. Additionally, the meter has a
feature that allows a remote computer to directly control the outputs of the
meter. Communication and bus capabilities are also available as option cards.
These include RS232, RS485, DeviceNet, and Profibus-DP.

The PAX2 includes a built-in USB programming port. With a Windows
based program, made available by Red Lion Controls, configuration data can be
downloaded to the PAX2 without the need of any additional option cards.
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, or
any setpoint value.
After the meter has been initially configured, the parameter programming
may be locked out from further modification in its entirety, or allowing selected
values accessible for quick entry.
The meter has been specifically designed for harsh industrial environments.
With NEMA 4X/IP65 sealed bezel and extensive testing of noise effects with
regard to CE requirements, the meter provides a tough reliable application
solution.
