1. Delay time range: minimum 0.1 seconds, maximum 999 minutes adjustable. Working voltage: AC 110V-250v common mains voltage. Signal source: low level active (common power supply negative trigger, button, NPNP sensor, PLC signal, etc.). Output capability: can control equipment within DC 30v5A or within AC 220v5A. Output optocoupler isolation, enhance anti-interference ability, power consumption, industrial-grade circuit board, set parameters will be remembered forever after power off.2. P-1: The signal triggers the relay to pull in, the time is up, the relay is disconnected, during the delay period. A: Re-triggering is invalid B: Re-triggering and re-timing C: Re-triggering the relay reset to terminate the timing3. P-2: The signal triggers to start timing time T1, when the time is up, the relay pull-in time T2 is disconnected (reset). A: Re-triggering is invalid B: Re-triggering and re-timing C: Start delay without triggering power-on4. P-3: Circular use: T1 is turned on, T2 is turned off, infinite loop. T1 and T2, the time is adjustable. If a parameter is turned on or off is 0, the power-on delay is turned on or the power-on delay is turned off without cycling. A: The relay is turned on immediately after power-on B: The relay is turned off first and then turned on after power-on5. P-4: There is a signal, the relay pulls in, keeps pulling in, the signal disappears, the timing starts, the time is up, the relay is disconnected, during the delay period, the signal is given again, the delay is canceled, the relay is held, the signal disappears, and the timing is restarted.Button:K1: function selection key: long press the K1 key for 2 seconds, P-* appears, short press K1 to select the mode, press K2 to enter the modeK2: Shift key: Press to adjust the position of the flashing digital tube, which digital tube flashes, K3 will adjust the value of the flashing digital tube. Until K2 is pressed, the digital tube no longer flashes, the set time is completed, the set time is automatically saved and the memory is powered off.K3: When the digital tube is flashing: K3 adjusts the digital change, 0 to 9 change in sequence.When the nixie tube display is normal: K3 adjusts the decimal point position, the decimal point in the one digit represents 0 to 999 minutes; in the ten digit, it represents 0 to 99.9 seconds; no decimal point represents 0 to 999 secondsNote1: After the working mode is selected, short press K1 to switch between A, B, and C of the function. The digital tube will not display A, B or C. After short pressing K1, you can only know by triggering the test for the signal. Default is ANote 2: Functions P-2 and P-3 have 2 sets of time to be adjusted. Press K2 six times as a cycle, the first three times to adjust one time, and the last three times to adjust another time.(Blue light on means setting the time for the relay to pull in, and blue light off means setting the time for the relay to open.)color:BlueMaterial:PCBsize:65x40mmPackage Contents:1 x Relay Timing ModuleOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
