12V 1 CH Timer Delay Control Relay Module Power Supply Board Switch 4 Bits LED Digital Tube Display Relay Module

Desription:
1: Product model: YYA-1
2: Working voltage: DC 12V, in addition DC5V or DC24V
3: Output capability: it can control equipment within DC 30v 5A or AC 220v 5A
4: Quiescent current: 20mA Working current: 50mA
5: Service life: 100,000 times;
Working temperature: -30~85℃
Size: 64.5mm*38.9mm*18.5mm
6: Output optocoupler isolation, enhance anti-interference ability, power consumption, industrial-grade circuit board, set parameters will be remembered forever after power off.
Special attention: The relay output is a passive contact, no live output, and controls the on-off function of a line.

P1-1 working mode: start timing when the power is turned on, when the time is up, the relay is turned on.
P1-2 working mode: when the power is turned on, the relay is turned on and starts timing, and when the time is up, the relay is turned off.
P1-3 working mode: connect X, disconnect Y, infinite loop. The user can successively set the time X, Y, the number of cycles N; (Note: when the number of times N is 0, it represents an infinite cycle)

Description of button settings:
K1: function key: long press K1 to display P-1~3, then short press K1 to select the function mode, after selecting, press K2 to enter the mode.
 
K2: 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 nixie tube no longer flashes. Long press K2 to turn off the digital tube display.
 
K3: When the digital tube is flashing: K3 adjusts the digital change, 0 to 9 change in sequence.
When the digital tube display is normal: K3 adjusts the position of the decimal point, the decimal point in the one digit represents 0 to 9999 minutes; in the ten digit, it represents 0 to 999.9 seconds; no decimal point represents 0 to 9999 seconds.

Note: 
Function P-3 has 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.)
