TB20 Energy Meter

Input voltages (3 phases + N) can be connected directly to the module.
In addition to general status information, the module’s configuration can be used to show up to 7 readings in the input image table.
In the event of a system failure, the controllable meter’s values will be stored in non-volatile memory.

Input currents are coupled through current transformers. The Energy Meter module is designed for a maximum secondary current of 5 A.
Other rated secondary currents, as well as the use of Rogowski coils, are available upon request.

Note: Individual modules cannot be combined with the IO systems of other manufacturers.
