Features 1、[Anti Interference] The input and output adopt optocoupler to isolate the quotient to enhance the anti interference ability. 2、[Function] This time relay module has the function to add the anti reverse connection function of the power supply. 3、[Industrial Grade Board] To ensure stability, industrial grade circuit board, set parameters can be remembered forever. 4、[Signal] The signal terminal can keep the signal for a long time, and the output is equivalent to a passive contact switch. 5、[Current] The static current of the module is 20mA, the working current is 0mA, and the service life is more than 100,000 times. Specification Item Type: Relay Module Material: Plastic Product Size: Approx. 64.2 x 40 x 18.5mm / 2.5 x 1.6 x 0.7in Relay Capacity: AC 220V10A or DC 30V10A Static Current: 20mA Working Current: 50mA Signal Type: 0V Low Level or Switch Signal Service Life: ≥100,000 Times Working Temperature: -40~85℃ Working Mode Selection: After Turning on the Power, Long Press K1 for 2 Seconds to Enter the Selection Function Mode, P1—1~p1—4 Can Be Selected, P1-1 Working Mode: the Signal Triggers the Relay to Close. when the Time is Up, the Relay is Disconnected. the User Can Set the Time T for the Relay to Close. Press K2 and the Hundred Digit Will Start to Flash. Press K3 at This Time, and the Hundred Digit Will Change. ; Press the K2 Ten-digit Number Tube to Start Flashing, Press K3 at This Time, the Ten-digit Number Changes; Press K2 the One-digit Number Tube to Start Flashing, Press K3 at This Time, the One-digit Number Changes; Press K2 Again, ;digital the Tube No Longer Flashes, Press K3 at This Time, the Decimal Point Shifts, the Decimal Point in the Ones Place Means 0 to 999 Minutes, the Tens Place Means 0 to 99.9 Seconds, and No Decimal Point Means 0 to 999 Seconds; After the Selection is Made, the Time Setting is Now Complete. Short Press K1 to Enter the Fine Adjustment Setting of the Function. the Default Trigger Period is Invalid. Press K1 to Activate the Trigger During the Delay Period (re-timing). Press K1 to Reset During the Delay Period (timing Off, Relay Reset). Press Again to Repeat the Default Setting for the First Time. P1-2 Working Mode: the Signal Triggers and Starts Timing X Time when the Relay is Closed and Y is Disconnected. the User Can Set the Time X and Y of the Relay Pull-in; the Time Setting is Similar to P1-1 Except That the Blue Light is on to Set the Relay Pull-in Time, and the Blue Light is off to Set the Relay off Time. Short Press K1 to Enter the Fine Adjustment Setting of the Function. the Trigger is Invalid During the Default Delay Period, and the Trigger is Valid During the Delay Period by Pressing K1 (re-timing). Press Again to Repeat the Default Setting for the First Time. P1-3 Working Mode: Turn on for X Seconds, Turn off for Y Seconds, Infinite Loop. the User Can Set the Time X and Y for the Relay to Close; the Time Setting is Similar to P1-2. Short Press K1 to Enter the Fine Adjustment Setting of the Function. First Turn on X, Turn off Y Seconds, Press K1, Turn off X First, Turn on Y Seconds, and Press Again to Repeat the Default First Setting. P1-4 Working Mode: the Signal Triggers the Relay to Close but Does Not Start Timing. the Trigger Signal Disappears and Starts Timing T. when the Time is Up, the Relay is Disconnected; During the Delay Period, the Signal is Given Again, the Delay is Canceled, the Pull-in is Maintained, and the Signal Disappears. Restart Timing; (equivalent to Start Timing when the Button is Released, Often Used for Power-off Delay). the User Can Set the Time T for the Relay to Close; the Time Setting is Similar to P1-1.
