M-Bus Interface DRM-M
Additional communication modules for energy-meters (DRB-80-3P)
The M-Bus interface (1 module wide, DIN rail mount) is intended for connecting the energy meter to M-Bus. M-Bus is a standard widely used for remote reading of various types of consumption meters and sensors. The interface receives the measurement data from the energy meter by means of the infrared port available on the side of the meter itself, and gets the power supply from the bus, so that only the bus wiring (a two-wire standard telephone cable) must be connected, no additional wiring is required. The interface is suitable for both single-phase and three-phase energy-meter.
M-bus interface is for remote reading of all of the energy, power, voltage, current, frequency, power factor registers. Status byte are available as well, containing information about the status of the energy-meter (running tariff nominal, voltage and current range overflow).
Commands can be sent via M-Bus to the interface for resetting the energy accounts. Commands are enabled only on relevant measuring instruments models.
