Eastron SDM630 V3 3-Phase Bidirectional

Eastron SDM630 Modbus V3 can measure and display various electrical parameters including current, voltage, power, frequency, power factor, energy, harmonic distortion and more. It supports measuring electrical energy in both directions - to the grid and from the grid (4-quadrant measurement). Its large LCD display with blue backlight makes it very easy to monitor current measured values ​​and quickly obtain the necessary information.

The ability to connect up to 30 Modbus RTU devices to 1 bus (provided that they share the same Modbus communication parameters, and each has a unique Slave ID set).

Connection to Modbus RTU

When connecting multiple devices to 1 bus, do not forget to change each of them in the module's service settings its Slave ID (to a unique number (1 to 247).

Slave ID setting

Use the ⬆️ and ⬇️ buttons to go to the "Set Addr" menu.

Confirm with the E ↵ button.

Use the ⬆️ and ⬇️ buttons to set the new Slave ID address.

Confirm the new address with the E ↵ button.

V TapHome when adding Eastron SDM630 from the template (or in the module settings) do not forget to use the same Slave ID address.
