DSA-LRM Continuous Voltage Indicator LRM-System

The DSA-LRM continuous voltage indicator is a plug-in indicator for the LRM system. It allows absence of voltage to be checked on the basis of capacitively sensed voltages.

Technical description:

  • No external power required
  • Voltage indication by flashing red LED
  • All-insulated system (IP66) made of impact-resistant plastic
  • Integrated connector pins with seal to the interface
  • In-service test possible with Euro-Test LRM
  • Suitable for all climate zones
