Product Application:

this product adopts dual signal relay,with 1 set of coils, 2 sets of normally open and normally closed synchronous control relay, this modulethere are 2 triggers and 4 triggersnormally openand normally closed control,it is often applied to single chip microcomputer signalling control, small current motor forward and reverse control, PLC control, electronic enthusiasts learning, etc. It can also be developed and used by Arduino accessories.

Product Introduction:

1. Adopt the original Huike HK19F dual signal relay;

2. The input terminal only has 2 triggers, but there are 4 Switch outputs;

3. The output terminal of relay has 4 common terminals, which are usually open and closed, and 4 autonomous working;

4. High quality high temperature resistant PA wiring terminal is adopted, and the quality is very excellent;

5, with relay snap-in working status indicator light;

6. Use SS8050 original triode as switch tube, which can ensure the quality of large current;

7. The high level trigger of this module is triggered by DC positive pole.

Electrical parameters:

1. Power supply: 5V DC

2. Static current: less than 5mA

3. Maximum power with load: 1.5W

4. Load capacity of relay: 125VAC 1A(125W AC) or 30VDC 2A(60W)

the actual operating power should be within 70% of the nominal relay to avoid affecting the service life

5, the relay maximum life span: 1 million times

the interface instructions:

1. VCC: connect to the positive pole of DC power supply. This product is a continuous voltage of 5V, (according to the voltage requirements printed on the relay, our company has three types: 5V/12V/24v. The printed 05VDC is connected to 5V DC, 12VDC is connected to 12V DC, and 24VDC is connected to 24V DC).

2. GND: connect to the negative pole of DC power supply.

3. IN: signal trigger terminal. This module is triggered at a high level, that is, it is connected with the positive pole of the power supply, and the relay is attracted.

4. NC: the normally closed end of the relay. The relay has no suction fashionable, and the normally closed end is connected with the common end.

5. C(COM): relay common end.

6. NO: the normal beginning of the relay, the relay sucks fashionable, and the normal beginning is connected with the common end.
