Eastron SDM630 Series, SDM630-MB, SDM630-MB-2T Manual

Introduction

Product Introduction

SDM630 Mbus series including models: SDM630-MB & SDM630-MB-2T.
The meter measures and displays the characteristics of single phase two wire (1p2w), three phase three wire (3p3w) and three phase four wire (3p4w) supplies, including voltage, frequency, current, power, active and reactive energy, imported or exported. Energy is measured in terms of kWh, kVArh. Maximum demand current can be measured over preset periods of up to 60 minutes.
These units are Max. 100A direct connected and do not need to connect with external current transformers(CT). An M-Bus communication port is available on the meters for remote data transmission. SDM630-MB-2T also offers a 2 tariff port for dual power source measurement.

Outputs

M-bus Communication
The meter provides an M-Bus port for remote communication. The protocol fully comply with EN13757-3. The following communication parameters can be configured via M-bus communication:

Dual Source Measurement - 2 Tariffs
SDM630-MB-2T can measure energy from two different power supplies upon detection of a 230V voltage signal. For example, when public grid is power off and electric generator is on, the meter switches to tariff 2 measurement automatically.
The meter can also be used as a tariff meter. The tariff is controlled by an external time relay.

Pulse output
The meter is equipped with pulse output, which is fully isolated from the inside circuit. That generates pulses in proportion to the measured energy. The pulse output is polarity dependent, passive transistor output requiring an external voltage source for correct operation. For this external voltage source, the voltage shall be 5-27V DC, and the maximum input current shall be 27mA DC.
ATTENTION: Pulse output must be fed as shown in the wiring diagram on the left.
Scrupulously respect polarities and the connection mode.
Opto-coupler with potential-free SPST-NO Contact.
Contact range: 5~27VDC
Max. current Input: 27mA DC
