Features:
LED 3 digits display， intelligent control， time relay/delay function.
Realize high frequency， fast on-off circuit.
During the on-off process， will not produce any noise.
No electric spark， no electromagnetic interference.
The last setting parameters can be memorized after power off.
Signal terminal voltage signal can be maintained for a long time.
Applied to control motor， bulb， LED light string， mini pump， etc.

Working modes selection: after power on， long press K1 for 2s， later into the selection of modes: P1~4; K2 to enter the mode.
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;
P-4: The relay opens when a signal triggers， when the trigger signal disappears， digital countdown begins， and the relay closes when the time is up.
