Eastron SDM630 Modbus V2 meters with backlit display are advanced multifunctional devices designed for bidirectional measurement of electrical energy in single-phase and three-phase installations. In addition to the two-way energy flow (export and import), the SDM630 Modbus V2 meters also allow the registration and reading of many other network parameters. The meter has an RS-485 connector, so the measured values can be easily read using the Modbus-RTU protocol. In addition, it has two pulse outputs, including one customizable. The device measures and transmits information on parameters such as: voltage (V), frequency (Hz), current (A), energy (kWh/kVArh) introduced into the network (export), withdrawn (import) and total.
