ION7300 series – compact, cost effective, small format-configurable meters for power circuits

The ION 7300 Series offer a choice of feature sets through three models:

  • ION7300: power and energy metering, harmonics measurement (to 15th), analogue I/O, digital outputs, RS-485 port, and web server (Ethernet option only).
  • ION7330: adds event logging, min/max logging, 32-channel historical logging, setpoints, digital inputs, two RS-485 ports, modem, gateways, and email (Ethernet option only).
  • ION7350: adds 96-channels of historical logging, dip/swell monitoring, harmonics measurement to 31st, and waveform capture

Characteristics (some features are optional):

  • Panel-mount, LCD display (also available without display as a transducer version)
  • 3-phase, 4-quadrant metering, class 0.5 revenue-accurate (IEC & ANSI)
  • Voltage, current, power, frequency, power factor, demand, energy, and time-of-use metering
  • 64 samples/cycle waveform capture, dip/swell monitoring, harmonics measurement (up to 31st)
  • Sequence-of-events, coincident minimum/maximum, historical trends, and high-speed snapshot recording, 1 ms resolution timestamping
  • 4 analogue inputs, 4 analogue outputs, 4 digital status/counter inputs, 4 digital control/pulse outputs
  • 12 setpoints for alarms and control, 1 second response, multi-condition, call out on alarm
  • 5 communication ports: Ethernet, modem, 2 x RS-485, RS-485, front panel optical, PROFIBUS port (ION7300 only)
  • Protocols: Modbus RTU slave, Modbus TCP, DNP 3.0 (ION7330/7350 only), MV-90
  • Ethernet and modem gateways to 31 devices on RS-485 port
  • On-board web server, email for alarms and data logs
