LINETRAXX® RCMS150 series

LINETRAXX® RCMS150 series

  • As an alternative to the insulation test by means of periodic verification
  • AC/DC sensitive measured value acquisition type B
  • Pure DC fault evaluation
  • Applicable in a confined space
  • RS-485 with Modbus RTU or BMS
  • Data can be visualised

The six-channel RCMS150… residual current monitors are intended for measuring AC and DC fault currents in earthed power supplies which can be caused by insulation faults on loads. The devices are able to measure residual currents up to IΔ = 500 mA in a frequency range of DC…2 kHz. They are suitable for applications with a load current of up to 32 A and are thus intended in particular for monitoring final circuits. Two separately adjustable response values allow a distinction to be made between prewarning and alarm.

The devices feature an RS-485 interface with either BMS protocol or Modbus RTU which can be used to transfer measured values and alarm values. Setting parameters is also possible via this interface.

In order to meet the requirements of applicable standards, customised parameter settings must be made on the equipment in order to adapt it to local equipment and operating conditions. Please heed the limits of the range of application indicated in the technical data.
