RP Controller Expansion Module Energy Metering

RP controller expansion modules with power distribution capability support energy metering, which means that the module can measure the electrical energy consumption and power demand for the equipment connected to and supplied by the module.

The following RP controller expansion modules support energy metering:

  • High-voltage modules:

    • RP-C-EXT-DALI-M-PD

    • RP-C-EXT-0-10V-4-PD

    • RP-C-EXT-BL-4-HV-PD

    • RP-C-EXT-BL-SMI-4-HV-PD

    • RP-C-EXT-REL-4

  • Low-voltage modules:

    • RP-C-EXT-BL-2-LV-PD

    • RP-C-EXT-BL-SMI-2-LV-PD

The RP controller expansion module measures the energy consumption and power demand for the total load on the 230-277 VAC input. The energy consumed by the module itself is not included.

EcoStruxure Building Operation WorkStation has pre-configured BACnet analog input objects for measuring energy consumption and power demand, which can be used for trend logging and monitoring of value changes. Pour plus d'informations, voir Energy Metering Overview .

Energy consumption measurement

The RP controller expansion module measures the active energy. The measurement is performed according to the active energy measurement class 1 of the IEC 61557-12 standard. The active energy consumption is measured in Wh.

The typical measurement accuracy for the two categories of RP controller expansion modules and for their different measurement ranges is specified below.

Table : Typical Measurement Accuracy

Category of RP Controller Expansion Module

Typical Measurement Accuracy a

High-voltage modules

20 to 100 W: 5%
100 to 3000 W: 1%

Low-voltage modules

0.5 to 2 W: 5%
2 to 30 W: 1%
  1. At room temperature.
Power demand measurement

The power demand is measured in W. The power demand value is calculated once a minute.
