Taidacent 20PCS 2s-1000h Timing Mudule Multifunction Delay Trigger Time Delay Relay Chip C005 Delay Chip Taidacent 20PCS 2s-1000h Timing Mudule Multifunction Delay Trigger Time Delay Relay Chip C005 Delay Chip Shape about 12mm * 12mm, operating voltage 2v-5v, timing can be set to a minimum to a maximum of 2 seconds 1,000 hours, as indicated below description _x000D_ Function and Design 1. The circuit according to claim connected and set a good time resistance and supply voltage;_x000D_ 2. Before the power not trigger output is high;_x000D_ 3. Trigger terminal "falling" trigger effective immediately after the trigger output terminal goes low at the same time start the timer circuit;_x000D_ 4. Set the timer time to recover after the output terminal is high, wait for the next "falling" trigger;_x000D_ 5. The chip is not repeated triggered, meaning that_x000D_ continue to trigger in the period after the trigger chip output low if the trigger is invalid;_x000D_ 6. The trigger end of "falling" Trigger refers to the instantaneous change from high level to a low level;_x000D_ 7. General refers to VCC high voltage, low means 0-0.3v or GND,provided that they meet the level requirements can be;_x000D_ 8. trigger terminal can be connected to touch switch or microcontroller IO port or other digital circuits have a "falling" can effectively trigger;_x000D_ 9. The trigger can be designed to power, only to trigger a short circuit to ground, power is triggered, the time to recover after the output to a high level, waiting for the next_x000D_ Falling edge trigger again. _x000D_ Chip Feature: 1. The use of low-power CMOS technology, lead-free and environmentally friendly._x000D_ 2. Direct Push can output low LED_x000D_ (please add current limiting resistor), the output high may push transistor (please add current limiting resistor)._x000D_ 3. Available resistance adjusting timing, there are 8 * N (N = 0.1.2.3) times the timing selection,_x000D_ time can be adjusted from 2s-1000h._x000D_ 4. Optional trigger timing and triggering termination ground electric timer._x000D_ 5. standby output high, falling edge trigger, post-trigger output low, after the delay recovery high. _x000D_ _x000D_
