Rogowski coils and M-bus?

[MaBi]

Is there a meter for use with rogowski coils and that also have M-bus?

3555 and 3565 only have Modbus and BACnet

Hi @MaBi 

There is no single meter model that supports both Rogowski coil and M-Bus communication simultaneously.

The Acti9 iEM3000 series offers different models with various current input and communication protocol combinations:

Rogowski Coil Models:

Meters that accept Rogowski coil current inputs, such as the iEM3555 and iEM3565 models, are listed as having Modbus RTU or BACnet communication, respectively.

M-Bus Models:

Meters that support M-Bus communication, such as the iEM3135, iEM3235, and iEM3335 models, typically use direct connect (up to 63A or 125A) or Current Transformer (CT) inputs, not Rogowski coils.

The series is designed to offer flexibility by having different models for different combinations of current sensors and communication protocols, but the Rogowski coil models appear to be paired with Modbus or BACnet, while M-Bus models are generally paired with direct or standard CT inputs.

Hi!

Thanks for your answer!

I cant for the world think of any reason, why they choose to use Modbus on the IEM3555, it is an old serial communication protocol and is totally obsolete today.
