Relay module self-locking relay module single-chip microcomputer control relay 5V12V24V

Press the trigger button to lock the relay in place. Press it again to disconnect the relay. Alternatively, an external trigger switch can be connected or triggered with a low level.
Control of household appliances, control of various household lighting fixtures, control of factory equipment, used for controlling various low current, high voltage, and high-power products.

 Product Features:
1. Adopting double-sided board design PCB;
2. Using a microcontroller for control, with stable and reliable performance, strong anti-interference ability, and no false triggering, the performance is far better than CD4013;
3. A high-power voltage regulator provides sufficient and stable voltage, and has sufficient heat dissipation holes to ensure long-term stable and reliable operation of the product;
4. Equipped with anti reverse power protection diode, short-term reverse power supply does not damage the product;
5. This product has three power versions to choose from: 5V, 12V, and 24V;
6. Use a Songle relay to control the load, which can withstand both 250V 10A (AC) and 30V 10A (DC) loads;
7. Equipped with a touch switch for product testing, directly verifying the stability of the product;
8. The trigger can also be connected to an external trigger switch, and the product is equipped with a wiring socket and leads, making it more convenient to use;
9. Other sensor modules can also be used for triggering, as long as it is a low-level trigger, it is effective and has more expanded functions;
Electrical parameters:
Power supply voltage: 5V, 12V, 24V three optional power supply current: greater than 100mA
Load: 250V 10A (AC) or 30V 10A (DC)
Lifespan: 1 million cycles
Product Instructions:
1. Connect the corresponding direct power supply according to the voltage version;
2. The power supply should be connected in reverse according to the wiring diagram requirements. Although there is a protective circuit, it cannot be connected in reverse for a long time;
3. The product uses a voltage regulator (5V without a voltage regulator) and slightly heats up, which is a normal phenomenon. The relay also has a normal heating phenomenon after long-term operation, which is a normal phenomenon;
4. The load power should leave a certain margin for the relay load, and avoid environments with high power (around 2000W) and long-term operation, which may have a certain impact on the product life.
