  • New upgrades to simplify, meeting the users\' needs.
  • Increase the power supply anti-reverse function.
  • LED 3 digits display, intelligent control, time relay/delay function.
  • The use of Opto isolated input and output, enhanced anti-jamming capability and consumption.
  • The last setting parameters can be memorized after power off.
  • Power saving function, one-key switch, can turn off the display.
  • To ensure stability, industrial grade PCB board.


After power on, long press K1 for 2s, later into the selection of modes: P1~3.

P-1: Monostable trigger delay, a signal to trigger relay, time is up, the relay disconnect;
P-2: A signal trigger and countdown begins, T1 seconds after, the relay open T2      seconds, then close;
P-3: Open T1 seconds, disconnect T2 seconds, infinite loop. Users can set the relay time T1 and T2;
