1、With liquid LCD display, the current mode is clear, very clear, simple and practical 2、All the second relay module delay disconnection circuit switching delay cycle timing circuit switch 0.01 seconds (limited to small) ~ 9999 minutes (limited to large) continuous adjustable 3、Has a button, the stop function (STOP button), with reversing protection, life free 4、Increase sleep mode, after you can, no operation within 3 minutes, automatically turn off the liquid LCD backlight: any button wake up 5、Can set different OP, CL, LOP parameters, which are independent, saved separately. You can save the parameters and do not need to be reset when you re-power Item Type: Relay Module Output Capability: the Device Can Control or Communicate within 220V 5A or within 220V 5A Quiescent: 15mA Operating Current: 50mA Help Life: 100,000 Times Work Temperature: 40 to 85℃ Size: Approx. 8.0 x 3.8 x 1.8cm / 3.1 x 1.5 x 0.7in Parameter Settings 1. Press Long Press the Set Button to Enter the Setup Interface; 2. First Set the Working Mode, the Working Mode is Flashing, and the Working Mode is Set by Short Pressing the Up / Down Button; 3. Press the Set Button, Select the Working Mode, and Enter the System Parameter Setting; 4. the System Parameters Are Flickering, Varying Parameters by Short Pressing the Up / Down Key; (note: Short Press Set in P-1 ~ P-3 Mode); 5. Short Press the Set Button, Enter the Corresponding Parameter Value Setting Interface, Short Press / Long Press the Up / Down Key to Change the Value Size, Modify the Interface in the Op / Cl Parameter Value, Can Switch the Decimal Point Position by Short Pressing the Stop, Change the Timing Unit ( 1s / 0.1 / 0.015 / 1min); 6. All Parameter Settings Are Complete, Press the Set Button, Save the Parameter Settings and Exit the Setting Interface The Main Function 1. Automatic Sleep Function: in the Run Interface, by Long Press the Stop Button, Start or Turn off the Automatic Sleep Function, the Interface Will Display "on" Or "off" Has Been 3 Seconds, Automatically Exits This Interface. 2. the Relay Function is Selected at the Run Interface, by Short Pressing the Stop Key, Starts or Turns the Relay Function, if the Relay Function is Turned Off, the System Flashes the Out; 3. Display Content Switches in P-5 P-6 Mode, Switch the Display Content (number of Runtime / Loop) by Short Pressing the Down Key. 4. There Are Seven Working Modes: P1. After the Signal is Triggered, the Relay Turns on the Op Time, then Disconnects; within the Op Time, the Signal is Triggered Again. (if the Signal Has Been Triggered, Only Once) P2. After the Signal is Triggered, the Relay Turns on the Op Time, then Disconnects; within the Op Time, the Signal is Triggered Again. (if the Signal Has Been Triggered, Only Once) P3. After the Signal is Triggered, the Relay is Turned on the Op Time. Since the Signal is Disconnected, the Signal is Triggered Again, and the Relay is Turned Off, and the Time is Stopped. (if the Signal Has Been Triggered, Only Once) P4. After the Trigger Signal, the Relay is Disconnected, the Relay Turns on the Op Time, After the Timing is Complete, Disconnect the Relay. (if the Signal Has Been Triggered, Only Once) P5. Given to the Trigger Signal, the Relay is Turned On, the Relay Disconnects the Cl Time, then Circulates the Above Action, the Loop is Again Given the Signal, the Relay is Disconnected, Stopped the Meter; the Number of Cycles (lop) Can Be Set P6. No Trigger Signals After Power-on, the Relay is Turned on the Op Time, the Relay is Disconnected by the Cl Time, Cycle the Above Action; the Number of Cycles (lop) Can Be Set; P7. Signal Hold Function if There is a Trigger Signal, the Time Clearance . (if the Signal Has Been Triggered, the Relay Has Been Turned On) 1 x Relay Module
