Time Relays

For many technical applications it is necessary to switch time-delayed loads on and off.

Two groups result:


  • Compressor air conditioning
  • Bus doors
  • Time-delayed motors


  • Radiator fan
  • Rear view mirror heating
  • Headlight cleaning
  • Timer
The exit that triggers the load is activated by an entry signal. The entry can be a switch or a button with plus or minus or a distribution voltage itself.

The exit can be either a relay (closing contact or changeover switch) or a power semi-conductor.

12 + 24 volt usage is possible.
