CMi-Box - Wireless M-Bus Receiver

CMi-Box Receiver

Infrastructure

Elvaco's Infrastructure segment is made up of products that enable collection, processing and delivery of meter data. Our M-Bus Gateways are used to read meters and deliver meter data in a suitable format to a receiving system. M-Bus Masters extends the number of meters a Gateway is able to use and Wireless M-Bus Receivers enables the Gateway to communicate with Wireless M-Bus meters. Elvaco also offers turn-key solutions, which are assembled, connected and ready to start using at delivery.

This CMi-Box is made up of a Wireless M-Bus Receiver mounted in a protective enclosure. The product can be used with a Gateway from Elvaco's CMe Series to enable communication with Wireless M-Bus meters. CMi-Box handles up to 800 meters, each one secured by individual encryption keys.
