CMeX12S is an M-Bus Master which, by providing additional supply current, 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. CMeX12S also supports integration with existing M-Bus systems through RS232. Cable is not included.

To ensure maximum longevity, the CMeX12S M-Bus Master for 128 meters consists of a robust polyamide casing and fail-safe, low-maintenance electronics. For ease of installation, the model can easily be mounted on a standard DIN rail.

A simple interface consisting of coloured LED lights shows whether the CMeX12S M-Bus Master for 128 meters is working correctly. The green LED lights up when the device is on, while the two yellow LEDs show that data is currently being transmitted and the red LED indicates an error message. The CMeX12S M-Bus Master for 128 meters is compatible with all M-Bus meters, ABB meters with IR interfaces and all CMe/CMeX series devices produced by Elvaco.
