Introduction to SENECA R203 and R204 Series Smart Energy Meters

This user manual provides detailed information for the SENECA R203 and R204 series of three-phase smart energy meters. These advanced devices are designed for the measurement and calculation of essential electrical quantities including voltage, current, power, energy, and harmonics.

The meters feature a universal current input, supporting various input types such as TA with current output, TA with voltage output, and Rogowski sensors. They are compatible with both single-phase and three-phase, 3- or 4-wire systems.

Connectivity is a key feature, with support for multiple industrial communication protocols, including Modbus (RTU/TCP), Profinet IO, Ethernet/IP, and OPC-UA, depending on the specific model. Additionally, certain models offer data logging capabilities and the ability to send data to the cloud via MQTT(s), HTTP(s), or FTP protocols.

Explore the comprehensive sections within this manual to understand device configuration, protocol changes using SENECA's Flex technology and Discovery Device software, dip switch settings, measurements, data logging, cloud connectivity, and network integration.
