RM-Mx
Interface module to integrate M-bus nodes into the Rail-Module-Bus
The LANCIER Monitoring Rail-Module-Bus is a robust sensor system.
Several measuring modules are mounted on a DIN rail and are directly connected to one another by means of plug-in contacts. The supply voltage, data analysis and control panel as well as their transmission to the remote measuring stations are carried out via the RM-Basic module.
The RM-Mx interface module integrates M-bus nodes into the RM-Module-Bus system, e.g. for reading of electric or power meters. The operating range might cover up to 10 km depending on the quality of the used copper monitoring pair.
The sensor’s thresholds are set at the server by the connected monitoring system.
An individually startable real-time measurement can be used for fault diagnostics.
