• Longest delay time : 00h:00m:01s – 99h:59m:59s
• 4 channel relay,each channel independently triggered independent delay, do not interfere with each other.
• 6 kinds of functional modules,  each functional module has three sub-modes  (no cycle, 2-99 cycle, always cycle).
• Input optical isolation.
• Power anti-reverse diode.
• High Q value SMD electrolytic capacitors.

Product Specifications:

• DC 5V control circuit,Wiring diagram below. “LOAD” may be LED lights, fans, toy car and other DC 5V equipment.
• DC 1-100V OR AC 85-265V control circuit,Wiring diagram below. “LOAD” may be LED lights, fans, motors and other DC AC equipment

User Instructions:

• Short press: press key time is less than 2 seconds;
• Long press: press key time more than 2 seconds;
• Status: working status , set status, power-saving status.
• working status : start work after powering.
• Displays the remaining time of 1 channel, the parameters can be displayed the “channel select” to set.
• Set status: short press the “SET” key to enter “channel select” Status. Short press “OK” button to exit the setting.
• power-saving status: in this Status,digital tubes don’t display,and other features work correctly. Long press “OK” button after 5 seconds to enter power-saving status, press again “OK” button for 5 seconds or re-power to exit power-saving status.
• Factory settings: press and hold “++” and “–” two button for 3 seconds, to restore factory settings, and the digital tube will turn open . After re-power , will run default parameters.

Settings:

• After power , the remaining time of digital display channel (default channel 1).
• Press “SET” button to enter “channel select” interface. In the “channel select” screen, then press “++”/”-” button to select channel to operate (relay). Press “OK” button will exit “channel select” screen, and save the current parameters. Press “SET” button into “parameter settings” interface.
• under “parameters” screen press “SET” button you can switch parameters. “++”/”-” Button to modify the parameters. Press the “OK” button to exit the “parameters” screen, and save the current parameters.
• Timer T1 T2 time minimum unit is second, so the timing range of T1 T2 is 99 hours 59 minutes 59 seconds.
• The number of cycles(Nx) is the number of cycles to perform an action triggered once(Nx = 00 indicates always cycle, Nx = 01 means no cycle).So you can set Number of cycles is: 1-99 times or always cycle.

Noun resolved:

• NO              : Relay normally open contact
• COM           : Relay common contact
• NC              : Relay normally closed contact
• Relay open : COM connect NO.
• Relay close : COM disconnect NO.   .

Function Mode:

• F0: After power-up, the relay close. Trigger input (IN1/2/3/4), relay open. T1 time delay close.
• F1: After power-up, the relay open. Trigger input, relay close. T1 time delay open.
• F2: After power-up, the relay close. Trigger input, delay time T1 and relay open. T2 time delay relay close.
• F3: After power-up, the relay open.Trigger input, delay time T1 and relay close. T2 time delay relay open.
• F4: After power-up, the relay close. After the delay time T1 and relay open. T2 time delay relay close.
• F5: After power-up,the relay open. After the delay time T1 and relay close. T2 time delay relay open.
