Application
The energy-meters “with a blue back-lighted LCD screen for prefect reading” are used to measure single-phase like
residential, Utility and Industrial application. The unit measures and displays various important electrical
parameters, and provide a communication port for remote reading and monitoring. Bi-directional energy
measurement makes the unit a good choice for solar PV energy metering.

Output
Pulse Output
The meter provides two pulse outputs. Both pulse outputs are passive type.
Pulse output 1 is configurable. The pulse output can be set to generate pulses to represent total / import/export
kWh or kVarh.
The pulse constant can be set to generate 1 pulse per: 0.001(default) /0.01/0.1/1kWh/kVarh.
Pulse width: 200/100(default)/60ms
Pulse output 2 is non-configurable. It is fixed up with Import kWh. The constant is 1000imp/kWh.
MBUS
M-Bus (Meter Bus) is a hierarchical system that consist of a Master,several Slaves and a pair of connecting
cables.All the devices are serially connected to the Bus,and all the the serial communication process on the Bus
are controlled by the major device.
The work status of Mbus are Data transmission status and idle work status,the data are bidirectional transported
between the Master and Slave.Only one Master is allowed to connect to the Bus when the data transmission
happens from Mater to Slave direction,and the Master need to provide power to the Bus. Household utility meters
can realize the function of remote meter reading via expanded to a Meter Bus and gain the ability of Bus
communication.
Eastron SDM220-Mbus single phase two wires meter supports MBUS remote communication function,its protocol
standard is EN 13757-3-2004.
Baud rate : 300, 600, 1200, 2400(default), 4800, 9600bps
Parity : NONE(default)/EVEN/ODD
