Descripción de la imagen


  • Electronic circuits designed to perform one or more delays used in relay switching or for special functions in switch cabinets.
  • 220Vac board power supply, 125Vac or 12Vdc power supplies are also available upon request.
  • Outputs through potential-free relay contacts, both in open and closed contact, to adapt to any application, two contacts for each timer, to control currents up to 5A.
  • The usual times of the timers are between 0.5 seconds and 7 seconds, because most of the applications where they are intended are for times that are between these margins, on request the time ranges can be extended.
  • All timers operate on power off, except the integrated 4 and 5 timer on the RTCR which includes run time functionality, configurable by multi-turn potentiometer from 15 seconds to 60 seconds.
  • In the case of the “travel time” timer, it will remain activated as long as the power supply voltage to the panel is maintained, thus preventing a new operation until the technician carries out the inspection of the maneuver, as indicated in the regulations.
  • Plug-in clamp-type connections for quick replacement and easy access to check signals while the circuit is live.
  • On the RTCR timers, light indicators for the activation of the different timers.
