RI-F550

Multifunction Analyser

Single phase or three phase

The RI-F550 Series is an advanced DIN 96 panel mounted multifunction meter with power analyser functions. Suitable for electrical parameter measurement and power quality analysis.

The meter has a full colour graphical display which provides clear indication in all light conditions.

Up to four plug-in modules can be added which allow the functionality of the meter to be extended with a wide range of both inputs and outputs. This enables full system integration with smart electricity distribution apparatus and energy management systems.

These meters may be used in single or three phase balanced or unbalanced load systems.

Quick select ‘touch’ buttons on the front of the meter allow the user fast access to the display page required.

Input and Output Features

  • The meter is equipped as standard with the following inputs and outputs:-
  • RS485 Modbus
  • Energy pulse output
  • 2 x AC Digital inputs
  • 2 x Relay outputs
  • Neutral current transformer input In addition to these core features the meters functionality can be expanded by the use of plug-in modules.

Plug-in Modules
The RI-F550 Series are provided with two connection points, each of which can accommodate two extension modules. This means that up to four modules may be connected per meter.
