Degson DSR-K32 Safety Timer Relay | 2NO+2NC Delay | PLe Cat.4 | SIL3

Degson DSR-K32 Safety Timer Relay – 2NO (Simultaneous) + 2NC (Delay) | PLe Cat.4 | SILCL3

The DSR-K32 is a DIN rail-mounted safety timer relay combining 2NO simultaneous contacts and 2NC delay contacts with an adjustable delay time of 0.1–80 seconds (default 10s). It supports E-STOP button and safety gate inputs, making it suitable for applications needing both immediate safety switching and time-delayed feedback monitoring in a single device.
