PM00A00IRI is an Eelectron energy measurement product or KNX interface for electrical monitoring. Energy-meter products are used to obtain electrical quantities and energy counters for monitoring, reporting and building energy-management applications. Depending on the exact variant, measurement may be single-phase or three-phase and may use direct connection or external current transformers; the interface model may transfer meter data to KNX. Meter accuracy class, current range, voltage range, tariff inputs, pulse outputs and communication interface must be checked against the exact model documentation. No current rating or certification is inferred from the code alone.
