Type RSI10


The RSI10 Remote Signalling Interface ensures reliable and earky detection of critical system conditions. Via an internal bus, it communicates with all circuit protectors installed in ControlPlex® Rack. Should one of circuit protectors disconnect the related load due to an overcurrent or similar, the RSI10 will externally indicate this status via a potential-free group signal, e.g. to a control room. It is the perfect way to minimise downtimes and reduce operational and maintenance costs.


  • Early failure detection due external alarm
  • Extended potential-free failure signalling (overvoltage, undervoltage, short circuit, overcurrent, excess temperature etc.)
  • Enhanced alarm indication on site by means of integral LED
  • Ease of retrofit without system downtimes
  • Conveniently accessible contact terminals on the front
  • Compatible for future system extensions with the RCI10 remote control and monitoring module
