RCMB330 Typ-B Wandler Modbus RTU

Combines measuring current transformer and evaluation device in one housing and offers a Modbus RTU interface with the features of the SensorPro series.

Application:

- Measurement of DC and AC residual currents in earthed systems (TN and TT systems)

- Measurement of residual currents IΔ = 10...500 mA in a frequency range of DC...100 kHz

- RS-485 interface with Modbus RTU for transmitting measurement and alarm values

Functions:

- Simple installation on top-hat rail or screw mounting

- RS-485 interface with Modbus RTU (read out measured values/parameterization)

- Frequency range DC...100 kHz

- Multi-color LED for operation and status messages

- Digitally adjustable filter for all-current sensitive measured value acquisition

- Separate evaluation of the AC and DC components as well as the effective value (RMS) of the residual current possible

- Installation without mechanical separation of the primary conductors

- Expansion of functionalities through software update via Modbus

- Insensitive to load current due to full magnetic shielding
