Degson DSR-K31 Safety Timer Relay – 1NO Delay Output | PLe Cat.4 | SILCL3

The DSR-K31 is a DIN rail-mounted safety timer relay — the key distinction from the DSR-K1x series. It features a 1NO delay output with an adjustable delay time of 0.1 to 80 seconds (default 10s), making it ideal for applications requiring timed safety functions such as delayed machine restart after an E-stop or safety gate reset.

DSR-K Series Quick Comparison:

  • DSR-K11: 1NO+1NC, no delay
  • DSR-K12: 3NO+1NC, no delay
  • DSR-K13: 2NO+2NC, no delay
  • DSR-K14: 2NO+2NC, no delay
  • DSR-K31: 1NO delay output, adjustable 0.1–80s ← This model
