UR-01 Versatile DIN-rail mounted relay

It is convenient to keep this relay in your tool bag as it allows you to solve a great number of tasks.

Versatile DIN-rail mounted relay

UR-01 Versatile DIN-rail mounted relay

It features switching contacts with galvanic and safety isolation for the switching of 230 V AC/16 A power loads, which can be used in one of eight selectable modes. The relay is designed for installation on a DIN rail and its characteristics are set with the use of switches under a cover.

It offers 8 functions:

  • Switching relay – standard NO/NC relay
  • Bistable relay – e.g. for lighting control from multiple locations with the use of buttons
  • Bistable relay with time limitation – e.g. for the control of lights from more places (but the light will not remain on longer than for the set time)
  • Delayed disconnection – e.g. for the rundown of a fan
  • Delayed switching on – the startup of an electric motor in star - delta mode.
  • Impulse by leading edge – activation of an appliance for a specified time
  • Impulse by trailing edge – e.g. to switch on a fan after turning the lights off
  • Regular impulses – at a set interval it will activate a device for 10 min – e.g. for the regular heating of a heating ladder in the bathroom
