Specification: Origin: Mainland China Power supply voltage: 5V, 12V, 24V (optional) Power supply current: greater than 100mA Load: 250V 10A (AC) or 30V 10A (DC) Life time: 1 million times Product weight: 25g Product size: About 50.4x26mm/1.98x1.02inch Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1 x Relay Module 1. Easy to Control and Operate: The relay can be controlled by simply pressing a button - one press locks it in place, and another releases it. Alternatively, it can be operated using an external switch or triggered by a low-voltage signal. This makes it good for controlling a wide range of devices, from household appliances to factory equipment. 2. Versatile Design: The relay features a double-sided PCB (printed circuit board) design, which ensures maximum durability and stability. It is also available in three different power versions: 5V, 12V, and 24V. 3. Reliable Performance: The relay uses a microcontroller for reliable and stable performance, with strong anti-interference capabilities that prevent false triggering. It also features a high-power voltage regulator and ample heat dissipation holes to ensure long-term reliability. 4. Built-in Protections: The relay comes equipped with a reverse polarity protection diode, which protects it from damage in case of accidental power supply connection reversal. It can handle loads up to 250V AC / 10A or 30V DC / 10A, ensuring safe and reliable operation.
