12V latching relay module
Parameters:
Power supply voltage: 12V
Power supply current: greater than 100mA
Load: 250V 10A (AC) or 30V 10A (DC) avoid high power (about 2000W)
Lifespan: 1 million times
Press the trigger button, the relay latches, press it again, the relay disconnects, and can also be externally triggered and low-level triggered
Suitable for small current control of household appliances, various household lamps, factory equipment and various high-voltage and high-power products
Features:
1. Using single-chip microcomputer control, stable and reliable performance, strong anti-interference, no error triggering, performance far exceeds CD4013
2. The high-power voltage regulator provides sufficient and stable voltage, and is equipped with sufficient heat dissipation holes to ensure that the product works stably and reliably for a long time
3 With anti-reverse protection diode, short-term reverse power supply will damage the product
4. Using relay to control the load, it can withstand loads below 250V 10A (AC) and 30V 10A (DC)
5. Equipped with a touch switch as a product test, directly test the stability of the product
6. The trigger can also be an external trigger switch, the product is equipped with wiring terminals and leads, which is more convenient to use
7. The trigger can also be triggered by other sensor modules, as long as it is a low-level trigger, it is effective, and the function is more expandable
Instructions for use:
1. According to the wiring diagram, first connect the DC power supply. The power supply cannot be reversed. Although there is a protection circuit, it cannot be reversed for a long time. During installation, the board can be fixed on an edge object according to the actual situation.
2. Connect the wires and connect the 5-28V power supply. After power on, the red LED light is on, indicating that it has been powered on normally. Press the test button, the relay is attracted and locked (hear "beep"), and the green LED light is on; press the relay again to disconnect and hear ("beep"), and the green LED light is off.
3. The trigger can also be externally connected to a momentary switch. This module is equipped with wiring terminals and leads, and can be directly connected to a momentary switch for use.
4. The trigger can also be triggered by other sensor modules. As long as it is a low-level trigger, it is effective, and there is more room for expansion.
5. The wiring should not be too thin to ensure that the wire can withstand the corresponding current.
6. This module uses DC-DC voltage regulation, and a slight heating is normal. It is normal for the relay to have normal heating after working for a long time.
7. The load power must leave a certain margin for the relay load. Avoid high power (about 2000W) and long-term working environment, which will have a certain impact on the product life
