CMeX10 M-Bus Master for 32 meters

CMeX10 is an M-Bus Master which, by providing additional drive strength, extends the number of meters a CMe Series Gateway is able to use. The product is equipped with a unique IR Pass Through feature which enables up to four CMe/CMeX Series devices to communicate via IR, by stacking them side-by side.

The CMeX10 - M-Bus Master for 32 meters is a connecting component for small M-Bus infrastructures that extends the number of meters a CMe Series Gateway can read. It makes remote meter reading particularly simple, reliable and cost-effective. However, the versatile M-Bus Master can also be used in larger-scale applications by stacking several components side-by-side. This makes it possible to expand the functionality of the existing metering infrastructure and lays the foundations for the straightforward recording and control of energy consumption.

 The CMeX10 - M-Bus Master for 32 meters is a small product that makes a big impact. Because of its compact design, it takes up very little space, is easy to install and reduces the amount of wiring needed. In addition, the CMeX10 - M-Bus Master for 32 meters is fitted with practical LEDs that show the current status of the master using simple colour signals. The model is compatible with classic M-Bus meters, ABB meters with an infrared interface and products from the CMe/CMeX series.

 Within an M-Bus infrastructure, this M-Bus Master supplies power to up to 32 meters/slaves, and processes their data. The impressive features of the CMeX10 - M-Bus Master for 32 meters include its cost savings, easy installation and maintenance and reliability.

 The CMeX10 - M-Bus Master for 32 meters is the ideal solution for connecting a small number of M-Bus slaves or expanding an existing infrastructure. If you have questions about the design, functionality or applications of the M-Bus Master, you can contact the expert team at Elvaco at any time.
