Hager enriches its KNX offer with a communication gateway for energy meters

The Franco-German brand thus confirms its presence in the KNX universe, and its desire to offer integrators, design offices and installers metering solutions that are always easier to install and connect.

Compatible with most Hager energy meters^[1] and all communication modes (pulse, Modbus, M-bus), the KNX TXF121 metering gateway is automatically connected using an infrared cell, as soon as it is positioned to the left of a Hager energy meter. It is also distinguished by its small footprint: a single module. It is easily integrated on the DIN rail of an electrical panel.

With the TXF121 gateway, it is now possible to make the energy meters communicating and to transmit on the KNX bus the data measured on single-phase networks up to 80A and on three-phase networks up to 125A in direct reading. It is also possible to return data from three-phase meters using current transformers.

In the context of tertiary installations (shops, shopping centers, hotels, etc.) or residential (villa, multi-residential), the TFX121 gateway allows in particular to know the state of the electricity network, the quality of energy, consumption by zone or by use.

This is a necessity, even an obligation within the normative framework of RT2012 as well as the environmental measures of IEC 60 364-8-1 and ISO 50 001, which require that buildings be equipped with measurement of consumption by zone or by use.

Self-powered by the KNX bus, the TXF121 allows all measurement data to be sent back to any KNX supervisor. It is then possible to target consumption, to establish a diagnosis to implement corrective actions and to anticipate drifts in order to avoid overconsumption.

Available in ETS programming for large projects, the KNX Hager metering gateway can also be configured in Easy mode, in order to allow quick and easy installations in a Hager product environment. Thanks to the new KNX TXF121 metering gateway, it is now possible to send electricity metering data to a Hager domovea supervisor configured in Easy.

Thanks to the new TXF121 communication gateway, professionals in the sector have access to a solution that is easy to install, in a small footprint, with a single reference suitable for the majority of meters in the Hager range.
