Rayleigh Instruments RI-D150 Multifunction Energy Meter - MID Certified


  • 100A direct connected
  • High-definition backlit LCD display
  • Four module width DIN rail mounted
  • Import and export active and reactive energy measurement - per phase and totals
  • 2 x pulse outputs
  • Modbus or MBus communication
  • LED pulse indication
  • Reversible Input direction (fed from top or bottom)
  • Generator tariff mode
  • Single-phase and three-phase network compatible


The RI-D150 is a MID approved DIN rail mounted multifunction energy meter. Suitable for monitoring energy consumption and many other electrical parameters in industrial and commercial applications. The meter also has a standby generator mode tariff. This allows the user to record the energy from a diesel generator, or similar, on a separate tariff without affecting the standard import/export register reading.

The meters may be used in single or three-phase, three, or four-wire systems and may be connected directly up to 100A ac, and do not require external current transformers.

The meter is MID approved (B and D) and may be used for billing purposes.

A high efficiency White backlit LCD display provides a clear indication of the measured values. Push-buttons on the front of the meter allow the user access to the display page required. A particularly useful feature is the ability to program whether the input current is supplied from the bottom or the top of the meter, making for a convenient installation.

The meter is currently available in two versions:-

  • With two pulse outputs and RS485 Modbus RTU communication
  • With two pulse outputs and MBus communication
