Product use:
Press the trigger button, corresponding relay lock, press, relay disconnect can also be eternal trigger switch, and 0V level trigger.

Product features:
1 adopt double sided board design PCB, 7 way independent self lock design;
2 stable and reliable chip is used to control, stable and reliable performance, strong anti-interference ability, will not trigger, the performance is far superior to CD4013;
3 with high power supply voltage regulator tube to provide sufficient and stable voltage, and has enough cooling holes, to ensure that the product long time stable and reliable work;
4 with anti - power supply connected to anti - protection diodes, short - time power supply to the product without any damage to the product;
5 the use of pine music authentic relay control load, in the 10A 250V (AC) and 10A 30V (DC) under the load can bear;
6 trigger can also be eternal trigger switch, the product is equipped with a terminal block, more convenient to use;
7 trigger can also be used to trigger other sensor modules, as long as the 0V or the power of the negative trigger are effective, the function has more etended;

Relay output contact with double - line, can withstand large current more secure
Electrical parameters:
Supply voltage: 12V (DC) supply current: more than 1000mA
Load: 10A 250V (AC) or 10A 30V (DC)
Life: 1 million times
Product instruction:
1 power supply to meet the scope of use, DC 12V;
2 power supply according to the requirements of the line, can not be reversed, although there is a protective circuit, but not a long time to reverse;
3 products using a voltage regulator tube is a slight fever, is a normal phenomenon, the relay for a long time to work there are normal heating phenomenon, is a normal phenomenon;
4 load power to give the relay load has a certain margin, should avoid high power (2000W) and a long time working environment, the product life will have a certain impact.
