Residual current monitors LINETRAXX® RCMS460/RCMS490 Digital input Each individual channel can be used for one of the following monitoring functions: • As digital input using a potential-free contact 1/0 • O r for current or residual current monitoring in combination with measuring current transformers. History memory in RCMS460-D, RCMS490-D The device utilises a history memory for failsafe storing of up to 300 data records (date, time, channel, event code, measured value), so that all data about an outgoing circuit or an area can be traced back at any time (what happened when). Analysis of harmonics...

Residual current monitors LINETRAXX® RCMS460/RCMS490 Kr BENDER Overview of device types

Residual current monitors LINETRAXX® RCMS460/RCMS490 Operating and display elements RCMS460-D The frequency response of the equipment can be set to a linear frequency response (up to the maximum frequency of Hz) if used for fire protection or to a frequency response in accordance with IEC 60990 for personnel protection. For plant protection, the residual current is measured up to the rated system frequency. The figure below shows the corresponding frequency response. Frequency curves L ED ALARM “2” lights up when the measured value falls below or exceeds the response value in a measuring channel...
