R203 Power Meter
Power Meter with Ethernet - Profinet - OPC UA
R203 Ethernet Power Meter Installation Manual
R203 is a versatile energy power meter with flexible input, capable of handling a wide range of current measurement inputs. It can accept current transformer inputs, direct voltages, and Rogowski sensors with voltage signals up to 333 mV. R203 can be used for multiple applications, including single-phase and three-phase 3/4-wire types, and is compatible with Modbus RTU, Modbus TCP, and versions available with OPC UA and Profinet protocol connectivity.
Available with a 24 VAC/DC or 230 VAC power supply, it features a compact design with a depth of only 32 mm, allowing a daisy-chain connection with automatic fault-bypass protection. The power meter can provide voltage (0..10Vdc) and current (0/4..20mA) output signals. It also offers advanced functionality for measuring harmonics up to the 55th order for a better understanding of power quality.
Thanks to their compatibility with Modbus RTU/TCP-IP, Profinet IO, Ethernet/IP, and OPC UA protocols, R Series energy power meters integrate seamlessly into any control infrastructure, ensuring maximum flexibility across a wide range of industrial applications
UNIVERSAL INPUT R203 and R204 are three-phase power meters enabling universal input signals with adjustable scales up to 600 Vac (voltage), 5A(CT with current output), 250 mV (CT with voltage output or Rogowski sensors)
DATALOGGER ENERGY COUNTER R203-(X)With support for MQTT, HTTP, and FTP protocols for data transmission, the R203 and R204 operate as data loggers (up to 30 variables per tag and approximately 55,296 samples) and event loggers with recording of up to 32,768 samples.
ENERGY COUNTER The analyzers are equipped with a digital pulse output and retentive memory for accounting for active, reactive, and apparent energy. Both digital inputs have a filter and a 32-bit incremental counter
DATA TRANSMISSION VIA MQTT, FTP, HTTP(s) The values acquired by the data logger can be sent directly to the cloud using the MQTT(s), Http(s), or FTP protocols. Transmission via MQTT also includes timestamps and thresholds.

Rogowski Coils
RC150 Rogowski coils are a flexible current transducer based on Rogowski principle. RC150 coils are available in different sizes and they can be used in applications, where traditional transducers are unable to be installed due to size and/or weight. The absence of magnetic core grants a wide frequency response.
