Features:
New upgrades to simplify， meeting the users' needs.
Increase the power supply anti-reverse function.
The use of opto isolated input and output， enhanced anti-jamming capability and consumption.
The setting parameters can be memorized after power off.
Signal terminal voltage signal can be maintained for a long time.
To ensure stability， industrial grade PCB board.

Notice:
Relay output is passive contact without charge output， and it control the on and off of the line.

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.
