Introduction
This document provides operating, maintenance and installation instructions of
SDM230 series made by Eastron Electronic Co., Ltd. The SDM230 series measure
and display the characteristics of single phase two wire (1p2w) network. The
SDM230 series covers 5 models:SDM230-Modbus,SDM230-Pulse,SDM230- Mbus,
SDM230-2T and SDM230-Std.
The bi-directional measurement makes the meter suitable for active and
reactive energy and power monitoring applications, and also perfect for solar
PV measurements. With RS485 Modbus and M-bus port, the meter is easy to remote
communication with other AMRI/SCADA systems.

1.2 Pulse output
The meter provides two pulse outputs. Both pulse outputs are passive type.
Pulse output 1 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:
0.001/0.01/0.1/1kWh/kVArh (default is 0.001 export kWh). Pulse width:
200/100/60ms Pulse output 2 is non-confgurable. It is fixed up with active kWh
(Imp). The constant is 1000imp/kWh.
1.3 RS485 Serial – Modbus RTU
RS485 serial port with Modbus RTU protocol to provide a means of remotely
monitoring and controlling the Unit.Set-up screens are provided for setting up
the RS485 port.
1.4 Mbus for SDM230-Mbus
This unit has an M-BUS serial port with M-BUS protocol to provide a means of
remotely monitoring and controlling the unit set-up screens are provided for
setting up the M-bus port.
1.5 2T by time relay for SDM230-2T
The unit has a time relay inside which can monitor if there is external 230V
signal input. If there is 230V signal input, the meter switches Tariff 2
measurement, otherwise it will measure as Tariff 1.
