Specification: _x005f_x000D_ Origin: Mainland China _x005f_x000D_ Type: Module _x005f_x000D_ NE555 Delay Module Monostable Switch Delay On/Off Switch (12V)Automotive Electrical Delay _x005f_x000D_ Product parameters: _x005f_x000D_ Main chip: NE555 _x005f_x000D_ Operating voltage: DC 12 volts _x005f_x000D_ Product size: 65*21*12mm _x005f_x000D_ Product features: _x005f_x000D_ 1. Turn on the power relay delayed suction. Specifically: after supplying 12V power to the relay, the relay will not absorb, the state of the relay output is: normally open and public disconnect, normally closed and public on; wait until after a delay of 1-10S (adjustable), the relay will absorb, at this time, the state of the relay output is: normally open and public on, normally closed and public off; as long as the module does not power, this state will always remain. _x005f_x000D_ 2. The delay time is adjustable, (0~10 seconds) _x005f_x000D_ 3. Increase the potentiometer can increase the delay time _x005f_x000D_ 4. Increase the capacitor C1 can increase the delay time _x005f_x000D_ 5. With input power indicator _x005f_x000D_ 6. With the relay suction indicator _x005f_x000D_ 7. Can control AC 220V / 10A equipment. (Is a large control device 2000W) _x005f_x000D_ 8. With relay renewal protection _x005f_x000D_ 9. delay time formula: T = 1.1RC. for example: capacitor 100UF resistance 100KT = 1.1 * 100000 * 0.0001 = 11 seconds _x005f_x000D_ Applicable scenarios: _x005f_x000D_ 1. The delay of the car equipment to turn on, the car ignition when the current is too large to burn the car equipment. _x005f_x000D_ 2. Need to have a sequence of starting occasions, multiple devices at the same time to start the current is too large burn electrical appliances. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ 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! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1Pc *Time Delay Relay Module 1.High-Quality NE555 Chip: The product uses high-quality NE555 chips, which are reliable and durable, providing stable performance for various applications. 2.Adjustable Delay Time: This product features an adjustable delay time, ranging from 0 to 10 seconds, providing users with flexibility and convenience in usage. 3.Increased Delay Time through Additional Components: The delay time of the product can be increased by adding a potentiometer or a larger capacitor (C1). 4.Multiple Indicators: This product comes with input power indicator lights and relay pull-in indicators, making it easy to monitor its status. 5.Versatile Compatibility: This product is compatible with various devices and can control AC 220V/10A equipment, making it suitable for various applications, such as car electronics and sequential startup devices.
