12V Protected Start Delay Relay Module 1. Power supply current: 10A 2. Power supply voltage: 12v24v 3. Use: Time delay 4. Module to achieve a certain time delay after power on and then output voltage or off output 5. Delay time 1~120 seconds adjustable, can be used for car recorder delay on, faucet after the water delay off and other applications 6. With power supply reverse protection, reverse connection will not burn 7. With repeat trigger button interface, can be connected to a button to achieve re-trigger the delay time, without the need to re-power 8. To adjust the delay time: the module is connected to the power supply, using a multimeter voltage class to measure the voltage value of the two points AB, every 0.039V for 1 second. For example, to adjust to 15 seconds, it is 0.039Vx15 = 0.58V, after adjusting the charging power off and then power on test, if the time value meets the requirements, the normal use of the module can be (default factory value of 1 minute) 9. Repeated triggering without power: If the application requires repeated triggering without power, a self-resetting button can be attached to the TR and G terminals of the board, and the module will repeat the delayed action once after each press of the button and release. 10. Dimensions: 52.8x32x18mm
