1 Channel 5V/12V/24V Latching Self-locking Relay Module With Touch Bistable Switch MCU Control 1 Channel Relay With Trigger Line

Product Usage:
Press the trigger button, the relay is closed and locked, press again, the relay is disconnected, you can also connect an external trigger switch, and trigger with low level.
Household appliances control, household lighting control, factory equipment control, used for the control of various low-current control high-voltage high-power products.

Features:
1. Using double-sided PCB design;
2. Using single-chip microcomputer as control, stable and reliable performance, strong anti-interference, no false trigger, performance is far superior than CD4013;
3. The high-power voltage regulator tube provides sufficient and stable voltage, and there are enough heat dissipation holes to ensure that the product works stably and reliably for a long time;
4. It has a protection diode to prevent the power supply from being reversed, and there is no damage to the product if the power is reversed for a short time;
5. This product is available in 5V, 12V, 24V three power versions;
6. Use genuine Songle relays to control the load, which can bear the load under 250V 10A (AC) and 30V 10A (DC);
7. With a touch switch as a product test, directly test the stability of the product;
8. The trigger can also be connected with an external trigger switch, and the product is equipped with wiring sockets and leads, which is more convenient to use;
9. The trigger can also be triggered by other sensor modules, as long as the low-level trigger is valid, and the function has more extensions;

Electrical parameters:
Power supply voltage: 5V, 12V and 24V three options Power supply current: more than 100mA
Load: 250V 10A (AC) or 30V 10A (DC)
Life: 1 million times

Product instructions:
1. Connect the corresponding direct power supply according to the voltage version;
2. According to the requirements of the wiring diagram, the power supply cannot be connected reversely. Although there is a protection circuit, it cannot be connected reversely for a long time;
3. The product uses a voltage stabilizer tube (5V without a voltage stabilizer tube), which is a normal phenomenon, and the relay has normal heating when it works for a long time, which is normal;
4. The load power should leave a certain margin for the relay load. Avoid high-power (about 2000W) and long-term working environments, which will have a certain impact on the product life.
