Summary edit

Description
English: Principial wiring diagram of pulse relay.
  • Bridge rectifier and thyristor VS1 should be chosen due to the load
  • R1, R2 and VD1 should be chosen due to VS1 datasheet
  • C1 and R3 should be chosen due to load's worktime
  • VD2 should be 5.1V only; otherwise you'll burn thyristor's gate
  • C2 should be chosen due to thyristor's gate current
  • S1 should be designed for your voltage, but current 1A is enough
  • C1 could be replaced by programmable controller, but joinpoint between VD1, VD2, C1 should be removed and connected to controller's.
Way of working is very simple - you put switch S1 on, after current gains to C1. After you put switch off, capacitor C1 begin to discharge. While C1 is discharging, thyristor VS1 keeps load switched on mode. After end of C1 discharging, VS1 switchs off the load.
