Features: With delay pull-in, delay disconnection, self-locking and triggered delay functions. With anti-reverse power supply function, the module will not be damaged if it is reversed. Timing duration can be arbitrarily set between 0.1 second and 120 seconds. The parameters can be saved, and the setting contents will not be lost after power off.
