Eastron's SDM630 Modbus V2 100A Three Phase Multifunction Energy Meter will measure and display all the fundamental electrical parameters for a cost-effective price, making it the ideal choice for sub-billing and energy management. The unit has built-in pulse and RS485 Modbus RTU outputs, and measures both single and three phase supplies.
The unit can monitor and display the following parameters of a Single Phase Two Wire (1P2W), Three Phase Three Wire (3P3W) or Three Phase Four Wire (3P4W) system.

This unit does not require a separate auxiliary supply as it is self-powered from the Voltage Inputs.
Three interfaces are provided:
The Modbus configuration (baud rate etc.) and the pulse relay output assignments (kW/kVArh, import/export etc.) are configured through the set-up screens
For Modbus RTU, the following RS485 communication parameters can be configured from the set-up menu:
Baud Rate | 2400, 4800, 9600, 19200, 38400 |
Parity | None(default) /Odd /Even |
Stop Bits | 1 or 2 |
RS485 Network Address | 3 Digit Number - 001 to 247 |
Modbus | Word order Hi/Lo byte order is set automatically to normal or reverse. It cannot be configured from the set-up menu. |
Influence Quantities are variables that affect measurement errors to a minor degree. Accuracy is verified under nominal value (within the specified tolerance) of these conditions.
