Red Lion Controls PAXH0000 PAX UNIVERSAL AC

Description

The PAXH (PAX AC True RMS Voltage and Current Meter) offers many features and performance capabilities to suit a wide range of industrial applications. The meter employs advanced technology for stable, drift-free readout, while incorporating features that provide flexibility now and in the future with plug-in option cards. The plug-in card options allow the opportunity to configure the meter for present applications, while providing easy upgrades for future needs.

The meters employ a bright 0. 56' LED display. The unit is available with a red sunlight readable or a standard green LED. 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 PAXH meter has four AC voltage input ranges (300 VAC max) and five AC current ranges (5 Amp max). The readout is scalable for applications using external shunts and current transformers. The input signal can be either AC coupled (rejecting the DC component of the signal) or DC coupled (measures both the AC and DC components of the signal).

Unlike many conventional average responding meters, the PAXH is a true RMS meter suited for the readout of both conventional sine waveforms, as well as distorted voltage and current waveforms. Its wide signal bandwidth and high Crest Factor capability allow the PAXH to accurately indicate waveforms such as pulse trains, ripple voltage, and chopped SCR heater waveforms, etc. Competitive average responding meters are frequently calibrated to read out the equivalent RMS value of a sinewave. However, distorted waveforms with Crest Factors greater than 2 or waveforms with DC components may lead to significant errors in these types of readouts.

Communication and Bus Capabilities are also available as option cards. These include RS232, RS485, Modbus, DeviceNet, and Profibus-DP. 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. With an RS232 or RS485 card installed, it is possible to configure the meter using a Windows based program. The configuration data can be saved to a file for later recall.

The meter has four setpoint outputs, implemented on Plug-in cards. The Plug-in cards provide dual FORM-C relays (5 A), quad FORM-A relays (3 A) or either quad sinking or quad sourcing open collector logic outputs. The setpoint alarms can be configured in modes to suit a variety of control and alarm requirements.

A linear DC output signal is available as a Plug-in card. The card provides either 20 mA or 10 V signals. The output can be scaled independent of the input. The features of the linear output cards are:

Once the meter has 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 meter has 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.
