Remote Displays
The SA300 can be ordered with an optional LED Remote Display Module (RDM) or LCD Remote Graphical
Module (RGM). Both have a fast RS-485 port and communicate with the SA300 through the Modbus RTU
protocol. Remote displays can be located at distances of up to 0.5 km from the device. The RGM can also be
ordered with an Ethernet 10Base-T port and can communicate with the SA300 through a local network.
The RDM has three six-digit windows with bright red LEDs well suited for dark areas. It allows the user to view
real-time RMS and harmonics measurements, status indication parameters, and perform basic setup
operations when installing and servicing the device.
The RGM is equipped with a color graphics LCD display and has extensive dialog capabilities, allowing the
user to view different fault and power quality information in a graphical form, such as waveforms, harmonic
spectrum, phasor and data trends, review latest fault and power quality reports for fast fault analysis, and
much more.
Upgradeable Firmware
The SA300 uses flash memory for storing device firmware that allows future upgrading of the device without
replacing any hardware component. The new features can be easily added to your device by simply replacing
the firmware through a local RS-232 port or Ethernet port.
